As part of the FieldFox B-series, the N9918B integrates cable and antenna tester (CAT), vector network analyzer (VNA), and spectrum analyzer (SA) functionality in a single field-portable instrument, designed to bring laboratory-grade microwave measurement capability to environments where benchtop instruments cannot be deployed.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe datasheet describes the FieldFox as equipment built to be carried into the field, with type-tested compliance to MIL-PRF-28800F Class 2 covering operating temperature, storage temperature, operating humidity, random vibration, functional shock, and bench drop. The IP53 ingress protection rating per IEC\/EN 60529 supports outdoor use in dust and light precipitation, and the instrument is type-tested for operation in explosive environments per MIL-STD-810G, Method 511.5, Procedure I. Typical applications supported by the datasheet's measurement coverage include cellular tower commissioning, antenna and cable verification, RF component characterization, and field spectrum monitoring.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eValueTronics International stocks, tests, and supports Keysight FieldFox analyzers including the N9918B from our 20,000 sq ft secure warehouse at 1675 Cambridge Drive, Elgin, Illinois. Every {{CONDITION}} N9918B leaving our facility has been inventoried, inspected, and prepared for shipment by our in-house team — not drop-shipped from a third party.

In 2014, Agilent further divided its operations, with the electronic measurement business becoming Keysight Technologies. Engineers may encounter FieldFox documentation, accessories, and service materials referencing both Agilent and Keysight branding depending on the production date.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eCompare Other Models in This Series\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe FieldFox B-series spans two analyzer architectures across the 4 GHz to 50 GHz range. The N991xB combination analyzers (N9913B through N9918B) integrate CAT, VNA, and SA capability with 30 kHz lower frequency limits, while the N993xB signal analyzers (N9933B through N9938B) share the same upper frequency tiers but are positioned as spectrum-focused instruments. The N995xB and N996xB microwave series extends combination and signal analyzer coverage to 32, 44, and 50 GHz with a 300 kHz lower frequency limit.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003ePer the datasheet, all FieldFox models share a common physical platform — 292 x 188 x 82 mm, 3.34 kg with battery, 6.5\" transflective color LCD-LED display, lithium-ion battery operation, LAN\/USB connectivity, and MIL-PRF-28800F Class 2 environmental compliance. Models differ primarily in upper frequency limit, included measurement modes (combination vs. signal analyzer), and available connector type at the test ports.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eEach new FieldFox model listed below is its own dedicated product page on ValueTronics with condition-matched pricing and availability. Use the comparison table to identify the model that fits your frequency range and measurement requirements, then navigate to the individual listing for ordering details specific to that unit.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe N9918B is the upper-frequency boundary of the N991xB combination analyzer line at 26.5 GHz. Per the datasheet, the 26.5 GHz models use 3.5 mm (m) test port connectors rather than the Type-N (f) connectors used on lower-frequency members of the series; Type-N is not offered on the N9918B combination analyzer. This connector choice supports the measurement performance and connector durability required at K-band frequencies.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eWithin the FieldFox B-series, primary differentiation across models is upper frequency limit: 4 GHz (N9913B\/N9933B), 6.5 GHz (N9914B\/N9934B), 9 GHz (N9915B\/N9935B), 14 GHz (N9916B\/N9936B), 18 GHz (N9917B\/N9937B), 26.5 GHz (N9918B\/N9938B), 32 GHz (N9950B\/N9960B), 44 GHz (N9951B\/N9961B), and 50 GHz (N9952B\/N9962B). The datasheet specifies test port output power, dynamic range, DANL, phase noise, and amplitude accuracy separately for each model class.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe combination analyzers (N991xB, N995xB) include CAT and VNA capability with the spectrum analyzer offered as Option 233, while the signal analyzers (N993xB, N996xB) come configured as spectrum-focused instruments. Connector types vary by frequency tier: Type-N (f) for ≤18 GHz models, 3.5 mm (m) on the N9918B and optionally on N9938B, and 2.4 mm (m) on all 32\/44\/50 GHz models.

The FieldFox family covers frequency ranges from 4 GHz through 54 GHz across multiple model variants, and each unit is built to withstand harsh working conditions while delivering measurement performance the datasheet positions as correlating with high-performance benchtop instruments. The instrument is intended as a field-capable platform for measuring cables, antennas, filters, amplifiers, and modulated RF signals.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eFieldFox is positioned by the datasheet for cable and antenna test on cellular and microwave infrastructure, 5G deployment and field testing, satellite and radar coverage verification, beamforming verification with phased array antennas, radar and electronic warfare systems diagnostics, and field signal monitoring with wideband IQ capture. The datasheet specifically identifies hardware installation and maintenance, over-the-air signal quality verification, interference hunting, and characterization of pulsed RF signals as application areas the instrument is designed to address.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eValueTronics stocks and tests the FieldFox handheld analyzer family at our 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every unit we list passes through our in-house performance verification process before shipping, and our condition reports document what our technicians measured rather than what a prior seller described. We have been supplying test and measurement instruments to engineering teams, defense programs, university labs, and field service operations since 1992, and our breadth across more than 120 manufacturers means we can pair a FieldFox with the cables, calibration kits, antennas, and companion instruments a complete field measurement setup typically requires.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eBrand Heritage\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eKeysight Technologies was spun off from Agilent Technologies in 2014, and Agilent itself was created in 1999 when Hewlett-Packard separated its test and measurement business from its computing business. The HP–Agilent–Keysight progression means that FieldFox is a direct continuation of the Hewlett-Packard test and measurement engineering legacy, and calibration support, application engineering, and the broader product ecosystem are now provided under the Keysight name.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eCompare Other Models in This Series\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe FieldFox family is organized into two parallel product lines that share the same handheld chassis and user interface. Combination analyzer models — covering Cable and Antenna Test, Vector Network Analysis, and Spectrum Analysis — use model numbers in the N991x, N993x, N995x, and N912C ranges. Dedicated Spectrum Analyzer models use model numbers in the N993x, N996x, and corresponding C-series ranges. Both lines span frequency coverage from 4 GHz through 54 GHz, allowing a buyer to match the instrument's frequency ceiling to the highest frequency the application requires.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eAcross the family, the datasheet identifies three series generations: the legacy B-Series (now discontinued for several models and replaced by the C-Series equivalents), the current C-Series, and the newly introduced D-Series. The D-Series adds 120 MHz IQ streaming bandwidth, a Linux operating system, SFP+ 10-Gigabit Ethernet interfaces, a touchscreen for file management, and an enhanced DC power supply output. The C-Series N9912C in particular is positioned as a fully software-defined analyzer whose frequency coverage and instrument personality (CAT, VNA, or SA) are selected at purchase and upgradable by software license.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eEach FieldFox model on this page is its own product listing with condition-matched pricing. Every new FieldFox unit is selected and prepared per the condition standards described on the listing, and the model variants in the comparison table below reflect the different frequency ceilings and feature sets available across the family.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe most consequential difference between FieldFox models is the maximum frequency. The N991x and N993x combination and spectrum analyzer models cover up to 4, 6.5, 9, 10, 14, 18, and 26.5 GHz. The N995x and N996x models extend coverage to 32, 44, 50, and 54 GHz, with the highest-frequency 54 GHz models (N9953 and N9963) using 1.85 mm test port connectors. The 26.5 GHz N9918 and N9938 models, and the 32 GHz and above models, use 2.4 mm or 1.85 mm connectors; lower-frequency models in the family use Type-N (female) or 3.5 mm (male) test ports as printed on each model's port labeling.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eBeyond frequency coverage, models differ in their base instrument personality. Combination analyzers (N991x, N993x, N995x at the top of each frequency tier) include CAT and VNA capability as the base function with spectrum analysis available as an option. Dedicated spectrum analyzer models (N993x, N996x in the lower row of each frequency tier) include spectrum analysis as the base function and do not include the full VNA personality, although Option 320 provides reflection measurements including return loss and VSWR. The C-Series N9912C uniquely allows the buyer to choose CAT, NA, and\/or SA personalities at the time of purchase through the CA, NA, and SA option codes, with frequency upgrade available via the N9912CU upgrade product.\u003c\/p\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eModel\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eMax Frequency\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eType\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSeries\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e\u003cstrong\u003eN9915C\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e9 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9912C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 \/ 6.5 \/ 10 GHz (configurable)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer (Software-Defined)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9913C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9914C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e6.5 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp style=\"margin:0 0 8px 0; font-size:14px; color:#555;\"\u003eAdditional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eProduct Core \u0026amp; Specifications\u003c\/h2\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eGeneral — Physical\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e7.5 lb.

The FieldFox family spans nine frequency ceilings from 4 GHz through 50 GHz, with three primary product lines: combination analyzers (N991xA, N995xA series) that integrate Cable and Antenna Test, Vector Network Analyzer, and Spectrum Analyzer functions; dedicated microwave VNAs (N992xA series); and dedicated microwave spectrum analyzers (N993xA, N996xA series).

Keysight's test and measurement business traces its lineage to Hewlett-Packard's instrument division, which was spun off as Agilent Technologies in 1999, with the electronic measurement business subsequently separated as Keysight Technologies in 2014. FieldFox analyzers reflect this engineering heritage in their calibration architecture, which is based on the same calibration engine used in Keysight's PNA family of bench network analyzers.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eCompare Other Models in This Series\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe FieldFox family is organized into three product groupings sharing a common handheld platform. The N991xA combination analyzers (N9913A through N9918A) cover 30 kHz to frequency ceilings of 4, 6.5, 9, 14, 18, and 26.5 GHz, integrating Cable and Antenna Test, Vector Network Analyzer, and Spectrum Analyzer functions in a single unit. The N995xA combination analyzers (N9950A, N9951A, N9952A) extend the same combination architecture upward to 32, 44, and 50 GHz with a starting frequency of 300 kHz (CAT\/VNA) or 9 kHz (Spectrum Analyzer).\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eTwo specialized product lines address users whose application is dedicated to a single measurement domain. The N992xA microwave VNAs (N9925A through N9928A) are dedicated vector network analyzers covering 30 kHz through 9, 14, 18, and 26.5 GHz. The N993xA microwave spectrum analyzers (N9935A through N9938A) and N996xA microwave spectrum analyzers (N9960A, N9961A, N9962A) are dedicated spectrum analyzers covering the same frequency tiers as their combination-analyzer counterparts.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eEach model below is its own dedicated product page with new-matched pricing.

Combination analyzer models (N991xA, N995xA) support CAT, VNA, and Spectrum Analyzer measurements on a single unit, making them suitable for users who need multiple measurement domains in one instrument. Dedicated VNA models (N992xA) and dedicated Spectrum Analyzer models (N993xA, N996xA) are configured for users whose application is focused on a single measurement type.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eFrequency ceiling steps the price tier across the family. Within the combination analyzer line, the N9913A (4 GHz) through N9918A (26.5 GHz) cover the cellular, WiFi, and lower microwave bands; the N9950A through N9952A extend coverage through 50 GHz for millimeter-wave-adjacent applications. The N995xA models also offer broader spectrum analyzer measurement range, with a 9 kHz starting frequency versus 100 kHz on the N991xA.

The FieldFox family covers frequency ranges from 4 GHz through 54 GHz across multiple model variants, and each unit is built to withstand harsh working conditions while delivering measurement performance the datasheet positions as correlating with high-performance benchtop instruments. The instrument is intended as a field-capable platform for measuring cables, antennas, filters, amplifiers, and modulated RF signals.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eFieldFox is positioned by the datasheet for cable and antenna test on cellular and microwave infrastructure, 5G deployment and field testing, satellite and radar coverage verification, beamforming verification with phased array antennas, radar and electronic warfare systems diagnostics, and field signal monitoring with wideband IQ capture. The datasheet specifically identifies hardware installation and maintenance, over-the-air signal quality verification, interference hunting, and characterization of pulsed RF signals as application areas the instrument is designed to address.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eValueTronics stocks and tests the FieldFox handheld analyzer family at our 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every unit we list passes through our in-house performance verification process before shipping, and our condition reports document what our technicians measured rather than what a prior seller described. We have been supplying test and measurement instruments to engineering teams, defense programs, university labs, and field service operations since 1992, and our breadth across more than 120 manufacturers means we can pair a FieldFox with the cables, calibration kits, antennas, and companion instruments a complete field measurement setup typically requires.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eBrand Heritage\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eKeysight Technologies was spun off from Agilent Technologies in 2014, and Agilent itself was created in 1999 when Hewlett-Packard separated its test and measurement business from its computing business. The HP–Agilent–Keysight progression means that FieldFox is a direct continuation of the Hewlett-Packard test and measurement engineering legacy, and calibration support, application engineering, and the broader product ecosystem are now provided under the Keysight name.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eCompare Other Models in This Series\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe FieldFox family is organized into two parallel product lines that share the same handheld chassis and user interface. Combination analyzer models — covering Cable and Antenna Test, Vector Network Analysis, and Spectrum Analysis — use model numbers in the N991x, N993x, N995x, and N912C ranges. Dedicated Spectrum Analyzer models use model numbers in the N993x, N996x, and corresponding C-series ranges. Both lines span frequency coverage from 4 GHz through 54 GHz, allowing a buyer to match the instrument's frequency ceiling to the highest frequency the application requires.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eAcross the family, the datasheet identifies three series generations: the legacy B-Series (now discontinued for several models and replaced by the C-Series equivalents), the current C-Series, and the newly introduced D-Series. The D-Series adds 120 MHz IQ streaming bandwidth, a Linux operating system, SFP+ 10-Gigabit Ethernet interfaces, a touchscreen for file management, and an enhanced DC power supply output. The C-Series N9912C in particular is positioned as a fully software-defined analyzer whose frequency coverage and instrument personality (CAT, VNA, or SA) are selected at purchase and upgradable by software license.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eEach FieldFox model on this page is its own product listing with condition-matched pricing. Every new FieldFox unit is selected and prepared per the condition standards described on the listing, and the model variants in the comparison table below reflect the different frequency ceilings and feature sets available across the family.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe most consequential difference between FieldFox models is the maximum frequency. The N991x and N993x combination and spectrum analyzer models cover up to 4, 6.5, 9, 10, 14, 18, and 26.5 GHz. The N995x and N996x models extend coverage to 32, 44, 50, and 54 GHz, with the highest-frequency 54 GHz models (N9953 and N9963) using 1.85 mm test port connectors. The 26.5 GHz N9918 and N9938 models, and the 32 GHz and above models, use 2.4 mm or 1.85 mm connectors; lower-frequency models in the family use Type-N (female) or 3.5 mm (male) test ports as printed on each model's port labeling.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eBeyond frequency coverage, models differ in their base instrument personality. Combination analyzers (N991x, N993x, N995x at the top of each frequency tier) include CAT and VNA capability as the base function with spectrum analysis available as an option. Dedicated spectrum analyzer models (N993x, N996x in the lower row of each frequency tier) include spectrum analysis as the base function and do not include the full VNA personality, although Option 320 provides reflection measurements including return loss and VSWR. The C-Series N9912C uniquely allows the buyer to choose CAT, NA, and\/or SA personalities at the time of purchase through the CA, NA, and SA option codes, with frequency upgrade available via the N9912CU upgrade product.\u003c\/p\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eModel\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eMax Frequency\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eType\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSeries\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e\u003cstrong\u003eN9914C\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e6.5 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9912C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 \/ 6.5 \/ 10 GHz (configurable)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer (Software-Defined)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9913C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9915C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e9 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp style=\"margin:0 0 8px 0; font-size:14px; color:#555;\"\u003eAdditional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eProduct Core \u0026amp; Specifications\u003c\/h2\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eGeneral — Physical\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e7.5 lb.

The FieldFox family covers frequency ranges from 4 GHz through 54 GHz across multiple model variants, and each unit is built to withstand harsh working conditions while delivering measurement performance the datasheet positions as correlating with high-performance benchtop instruments. The instrument is intended as a field-capable platform for measuring cables, antennas, filters, amplifiers, and modulated RF signals.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eFieldFox is positioned by the datasheet for cable and antenna test on cellular and microwave infrastructure, 5G deployment and field testing, satellite and radar coverage verification, beamforming verification with phased array antennas, radar and electronic warfare systems diagnostics, and field signal monitoring with wideband IQ capture. The datasheet specifically identifies hardware installation and maintenance, over-the-air signal quality verification, interference hunting, and characterization of pulsed RF signals as application areas the instrument is designed to address.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eValueTronics stocks and tests the FieldFox handheld analyzer family at our 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every unit we list passes through our in-house performance verification process before shipping, and our condition reports document what our technicians measured rather than what a prior seller described. We have been supplying test and measurement instruments to engineering teams, defense programs, university labs, and field service operations since 1992, and our breadth across more than 120 manufacturers means we can pair a FieldFox with the cables, calibration kits, antennas, and companion instruments a complete field measurement setup typically requires.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eBrand Heritage\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eKeysight Technologies was spun off from Agilent Technologies in 2014, and Agilent itself was created in 1999 when Hewlett-Packard separated its test and measurement business from its computing business. The HP–Agilent–Keysight progression means that FieldFox is a direct continuation of the Hewlett-Packard test and measurement engineering legacy, and calibration support, application engineering, and the broader product ecosystem are now provided under the Keysight name.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eCompare Other Models in This Series\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe FieldFox family is organized into two parallel product lines that share the same handheld chassis and user interface. Combination analyzer models — covering Cable and Antenna Test, Vector Network Analysis, and Spectrum Analysis — use model numbers in the N991x, N993x, N995x, and N912C ranges. Dedicated Spectrum Analyzer models use model numbers in the N993x, N996x, and corresponding C-series ranges. Both lines span frequency coverage from 4 GHz through 54 GHz, allowing a buyer to match the instrument's frequency ceiling to the highest frequency the application requires.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eAcross the family, the datasheet identifies three series generations: the legacy B-Series (now discontinued for several models and replaced by the C-Series equivalents), the current C-Series, and the newly introduced D-Series. The D-Series adds 120 MHz IQ streaming bandwidth, a Linux operating system, SFP+ 10-Gigabit Ethernet interfaces, a touchscreen for file management, and an enhanced DC power supply output. The C-Series N9912C in particular is positioned as a fully software-defined analyzer whose frequency coverage and instrument personality (CAT, VNA, or SA) are selected at purchase and upgradable by software license.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eEach FieldFox model on this page is its own product listing with condition-matched pricing. Every new FieldFox unit is selected and prepared per the condition standards described on the listing, and the model variants in the comparison table below reflect the different frequency ceilings and feature sets available across the family.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe most consequential difference between FieldFox models is the maximum frequency. The N991x and N993x combination and spectrum analyzer models cover up to 4, 6.5, 9, 10, 14, 18, and 26.5 GHz. The N995x and N996x models extend coverage to 32, 44, 50, and 54 GHz, with the highest-frequency 54 GHz models (N9953 and N9963) using 1.85 mm test port connectors. The 26.5 GHz N9918 and N9938 models, and the 32 GHz and above models, use 2.4 mm or 1.85 mm connectors; lower-frequency models in the family use Type-N (female) or 3.5 mm (male) test ports as printed on each model's port labeling.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eBeyond frequency coverage, models differ in their base instrument personality. Combination analyzers (N991x, N993x, N995x at the top of each frequency tier) include CAT and VNA capability as the base function with spectrum analysis available as an option. Dedicated spectrum analyzer models (N993x, N996x in the lower row of each frequency tier) include spectrum analysis as the base function and do not include the full VNA personality, although Option 320 provides reflection measurements including return loss and VSWR. The C-Series N9912C uniquely allows the buyer to choose CAT, NA, and\/or SA personalities at the time of purchase through the CA, NA, and SA option codes, with frequency upgrade available via the N9912CU upgrade product.\u003c\/p\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eModel\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eMax Frequency\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eType\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSeries\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e\u003cstrong\u003eN9913C\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9912C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 \/ 6.5 \/ 10 GHz (configurable)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer (Software-Defined)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9914C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e6.5 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9915C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e9 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp style=\"margin:0 0 8px 0; font-size:14px; color:#555;\"\u003eAdditional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eProduct Core \u0026amp; Specifications\u003c\/h2\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eGeneral — Physical\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e7.5 lb.

The FieldFox family covers frequency ranges from 4 GHz through 54 GHz across multiple model variants, and each unit is built to withstand harsh working conditions while delivering measurement performance the datasheet positions as correlating with high-performance benchtop instruments. The instrument is intended as a field-capable platform for measuring cables, antennas, filters, amplifiers, and modulated RF signals.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eFieldFox is positioned by the datasheet for cable and antenna test on cellular and microwave infrastructure, 5G deployment and field testing, satellite and radar coverage verification, beamforming verification with phased array antennas, radar and electronic warfare systems diagnostics, and field signal monitoring with wideband IQ capture. The datasheet specifically identifies hardware installation and maintenance, over-the-air signal quality verification, interference hunting, and characterization of pulsed RF signals as application areas the instrument is designed to address.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eValueTronics stocks and tests the FieldFox handheld analyzer family at our 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every unit we list passes through our in-house performance verification process before shipping, and our condition reports document what our technicians measured rather than what a prior seller described. We have been supplying test and measurement instruments to engineering teams, defense programs, university labs, and field service operations since 1992, and our breadth across more than 120 manufacturers means we can pair a FieldFox with the cables, calibration kits, antennas, and companion instruments a complete field measurement setup typically requires.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eBrand Heritage\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eKeysight Technologies was spun off from Agilent Technologies in 2014, and Agilent itself was created in 1999 when Hewlett-Packard separated its test and measurement business from its computing business. The HP–Agilent–Keysight progression means that FieldFox is a direct continuation of the Hewlett-Packard test and measurement engineering legacy, and calibration support, application engineering, and the broader product ecosystem are now provided under the Keysight name.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eCompare Other Models in This Series\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe FieldFox family is organized into two parallel product lines that share the same handheld chassis and user interface. Combination analyzer models — covering Cable and Antenna Test, Vector Network Analysis, and Spectrum Analysis — use model numbers in the N991x, N993x, N995x, and N912C ranges. Dedicated Spectrum Analyzer models use model numbers in the N993x, N996x, and corresponding C-series ranges. Both lines span frequency coverage from 4 GHz through 54 GHz, allowing a buyer to match the instrument's frequency ceiling to the highest frequency the application requires.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eAcross the family, the datasheet identifies three series generations: the legacy B-Series (now discontinued for several models and replaced by the C-Series equivalents), the current C-Series, and the newly introduced D-Series. The D-Series adds 120 MHz IQ streaming bandwidth, a Linux operating system, SFP+ 10-Gigabit Ethernet interfaces, a touchscreen for file management, and an enhanced DC power supply output. The C-Series N9912C in particular is positioned as a fully software-defined analyzer whose frequency coverage and instrument personality (CAT, VNA, or SA) are selected at purchase and upgradable by software license.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eEach FieldFox model on this page is its own product listing with condition-matched pricing. Every new FieldFox unit is selected and prepared per the condition standards described on the listing, and the model variants in the comparison table below reflect the different frequency ceilings and feature sets available across the family.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe most consequential difference between FieldFox models is the maximum frequency. The N991x and N993x combination and spectrum analyzer models cover up to 4, 6.5, 9, 10, 14, 18, and 26.5 GHz. The N995x and N996x models extend coverage to 32, 44, 50, and 54 GHz, with the highest-frequency 54 GHz models (N9953 and N9963) using 1.85 mm test port connectors. The 26.5 GHz N9918 and N9938 models, and the 32 GHz and above models, use 2.4 mm or 1.85 mm connectors; lower-frequency models in the family use Type-N (female) or 3.5 mm (male) test ports as printed on each model's port labeling.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eBeyond frequency coverage, models differ in their base instrument personality. Combination analyzers (N991x, N993x, N995x at the top of each frequency tier) include CAT and VNA capability as the base function with spectrum analysis available as an option. Dedicated spectrum analyzer models (N993x, N996x in the lower row of each frequency tier) include spectrum analysis as the base function and do not include the full VNA personality, although Option 320 provides reflection measurements including return loss and VSWR. The C-Series N9912C uniquely allows the buyer to choose CAT, NA, and\/or SA personalities at the time of purchase through the CA, NA, and SA option codes, with frequency upgrade available via the N9912CU upgrade product.\u003c\/p\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eModel\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eMax Frequency\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eType\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSeries\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e\u003cstrong\u003eN9912C\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 \/ 6.5 \/ 10 GHz (configurable)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer (Software-Defined)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9913C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9914C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e6.5 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9915C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e9 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp style=\"margin:0 0 8px 0; font-size:14px; color:#555;\"\u003eAdditional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eProduct Core \u0026amp; Specifications\u003c\/h2\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eGeneral — Physical\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e7.5 lb.

The FieldFox family spans nine frequency ceilings from 4 GHz through 50 GHz, with three primary product lines: combination analyzers (N991xA, N995xA series) that integrate Cable and Antenna Test, Vector Network Analyzer, and Spectrum Analyzer functions; dedicated microwave VNAs (N992xA series); and dedicated microwave spectrum analyzers (N993xA, N996xA series). All FieldFox units share a common platform with a 6.5-inch transflective color LCD-LED backlit display sized for outdoor visibility.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eFieldFox analyzers are used for cable and antenna testing including distance-to-fault measurements, return loss, and VSWR characterization on transmission lines; vector network analysis with full S-parameter measurement (S11, S21, S22, S12) on RF components; spectrum analysis from 9 kHz (on N995xA\/N996xA models) or 100 kHz (on N991xA\/N993xA models) through the instrument's maximum frequency; and a range of specialized measurements available through licensed options including real-time spectrum analysis, I\/Q analysis, noise figure characterization, vector voltmeter operation, pulse measurements with external USB power sensors, and Over-the-Air cellular measurements (LTE FDD, 5GTF).\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eBrand Heritage\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe FieldFox product line is a Keysight Technologies platform. Keysight's test and measurement business traces its lineage to Hewlett-Packard's instrument division, which was spun off as Agilent Technologies in 1999, with the electronic measurement business subsequently separated as Keysight Technologies in 2014. FieldFox analyzers reflect this engineering heritage in their calibration architecture, which is based on the same calibration engine used in Keysight's PNA family of bench network analyzers.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eCompare Other Models in This Series\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe FieldFox family is organized into three product groupings sharing a common handheld platform. The N991xA combination analyzers (N9913A through N9918A) cover 30 kHz to frequency ceilings of 4, 6.5, 9, 14, 18, and 26.5 GHz, integrating Cable and Antenna Test, Vector Network Analyzer, and Spectrum Analyzer functions in a single unit. The N995xA combination analyzers (N9950A, N9951A, N9952A) extend the same combination architecture upward to 32, 44, and 50 GHz with a starting frequency of 300 kHz (CAT\/VNA) or 9 kHz (Spectrum Analyzer).\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eTwo specialized product lines address users whose application is dedicated to a single measurement domain. The N992xA microwave VNAs (N9925A through N9928A) are dedicated vector network analyzers covering 30 kHz through 9, 14, 18, and 26.5 GHz. The N993xA microwave spectrum analyzers (N9935A through N9938A) and N996xA microwave spectrum analyzers (N9960A, N9961A, N9962A) are dedicated spectrum analyzers covering the same frequency tiers as their combination-analyzer counterparts.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eEach model below is its own dedicated product page with new-matched pricing.

Combination analyzer models (N991xA, N995xA) support CAT, VNA, and Spectrum Analyzer measurements on a single unit, making them suitable for users who need multiple measurement domains in one instrument. Dedicated VNA models (N992xA) and dedicated Spectrum Analyzer models (N993xA, N996xA) are configured for users whose application is focused on a single measurement type.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eFrequency ceiling steps the price tier across the family. Within the combination analyzer line, the N9913A (4 GHz) through N9918A (26.5 GHz) cover the cellular, WiFi, and lower microwave bands; the N9950A through N9952A extend coverage through 50 GHz for millimeter-wave-adjacent applications. The N995xA models also offer broader spectrum analyzer measurement range, with a 9 kHz starting frequency versus 100 kHz on the N991xA.

Keysight's test and measurement business traces its lineage to Hewlett-Packard's instrument division, which was spun off as Agilent Technologies in 1999, with the electronic measurement business subsequently separated as Keysight Technologies in 2014. FieldFox analyzers reflect this engineering heritage in their calibration architecture, which is based on the same calibration engine used in Keysight's PNA family of bench network analyzers.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eCompare Other Models in This Series\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe FieldFox family is organized into three product groupings sharing a common handheld platform. The N991xA combination analyzers (N9913A through N9918A) cover 30 kHz to frequency ceilings of 4, 6.5, 9, 14, 18, and 26.5 GHz, integrating Cable and Antenna Test, Vector Network Analyzer, and Spectrum Analyzer functions in a single unit. The N995xA combination analyzers (N9950A, N9951A, N9952A) extend the same combination architecture upward to 32, 44, and 50 GHz with a starting frequency of 300 kHz (CAT\/VNA) or 9 kHz (Spectrum Analyzer).\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eTwo specialized product lines address users whose application is dedicated to a single measurement domain. The N992xA microwave VNAs (N9925A through N9928A) are dedicated vector network analyzers covering 30 kHz through 9, 14, 18, and 26.5 GHz. The N993xA microwave spectrum analyzers (N9935A through N9938A) and N996xA microwave spectrum analyzers (N9960A, N9961A, N9962A) are dedicated spectrum analyzers covering the same frequency tiers as their combination-analyzer counterparts.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eEach model below is its own dedicated product page with new-matched pricing.

Combination analyzer models (N991xA, N995xA) support CAT, VNA, and Spectrum Analyzer measurements on a single unit, making them suitable for users who need multiple measurement domains in one instrument. Dedicated VNA models (N992xA) and dedicated Spectrum Analyzer models (N993xA, N996xA) are configured for users whose application is focused on a single measurement type.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eFrequency ceiling steps the price tier across the family. Within the combination analyzer line, the N9913A (4 GHz) through N9918A (26.5 GHz) cover the cellular, WiFi, and lower microwave bands; the N9950A through N9952A extend coverage through 50 GHz for millimeter-wave-adjacent applications. The N995xA models also offer broader spectrum analyzer measurement range, with a 9 kHz starting frequency versus 100 kHz on the N991xA.

The N991xB combination analyzers (N9913B through N9918B) integrate CAT, VNA, and SA capability with 30 kHz lower frequency limits, while the N993xB signal analyzers (N9933B through N9938B) share the same upper frequency tiers but are positioned as spectrum-focused instruments. The N995xB and N996xB microwave series extends combination and signal analyzer coverage to 32, 44, and 50 GHz with a 300 kHz lower frequency limit.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003ePer the datasheet, all FieldFox models share a common physical platform — 292 x 188 x 82 mm, 3.34 kg with battery, 6.5\" transflective color LCD-LED display, lithium-ion battery operation, LAN\/USB connectivity, and MIL-PRF-28800F Class 2 environmental compliance. Models differ primarily in upper frequency limit, included measurement modes (combination vs. signal analyzer), and available connector type at the test ports.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eEach new FieldFox model listed below is its own dedicated product page on ValueTronics with condition-matched pricing and availability.

Per the datasheet, the 26.5 GHz models use 3.5 mm (m) test port connectors rather than the Type-N (f) connectors used on lower-frequency members of the series; Type-N is not offered on the N9918B combination analyzer. This connector choice supports the measurement performance and connector durability required at K-band frequencies.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eWithin the FieldFox B-series, primary differentiation across models is upper frequency limit: 4 GHz (N9913B\/N9933B), 6.5 GHz (N9914B\/N9934B), 9 GHz (N9915B\/N9935B), 14 GHz (N9916B\/N9936B), 18 GHz (N9917B\/N9937B), 26.5 GHz (N9918B\/N9938B), 32 GHz (N9950B\/N9960B), 44 GHz (N9951B\/N9961B), and 50 GHz (N9952B\/N9962B).

The FieldFox family spans nine frequency ceilings from 4 GHz through 50 GHz, with three primary product lines: combination analyzers (N991xA, N995xA series) that integrate Cable and Antenna Test, Vector Network Analyzer, and Spectrum Analyzer functions; dedicated microwave VNAs (N992xA series); and dedicated microwave spectrum analyzers (N993xA, N996xA series).

Keysight's test and measurement business traces its lineage to Hewlett-Packard's instrument division, which was spun off as Agilent Technologies in 1999, with the electronic measurement business subsequently separated as Keysight Technologies in 2014. FieldFox analyzers reflect this engineering heritage in their calibration architecture, which is based on the same calibration engine used in Keysight's PNA family of bench network analyzers.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eCompare Other Models in This Series\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe FieldFox family is organized into three product groupings sharing a common handheld platform. The N991xA combination analyzers (N9913A through N9918A) cover 30 kHz to frequency ceilings of 4, 6.5, 9, 14, 18, and 26.5 GHz, integrating Cable and Antenna Test, Vector Network Analyzer, and Spectrum Analyzer functions in a single unit. The N995xA combination analyzers (N9950A, N9951A, N9952A) extend the same combination architecture upward to 32, 44, and 50 GHz with a starting frequency of 300 kHz (CAT\/VNA) or 9 kHz (Spectrum Analyzer).\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eTwo specialized product lines address users whose application is dedicated to a single measurement domain. The N992xA microwave VNAs (N9925A through N9928A) are dedicated vector network analyzers covering 30 kHz through 9, 14, 18, and 26.5 GHz. The N993xA microwave spectrum analyzers (N9935A through N9938A) and N996xA microwave spectrum analyzers (N9960A, N9961A, N9962A) are dedicated spectrum analyzers covering the same frequency tiers as their combination-analyzer counterparts.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eEach model below is its own dedicated product page with new-matched pricing.

Combination analyzer models (N991xA, N995xA) support CAT, VNA, and Spectrum Analyzer measurements on a single unit, making them suitable for users who need multiple measurement domains in one instrument. Dedicated VNA models (N992xA) and dedicated Spectrum Analyzer models (N993xA, N996xA) are configured for users whose application is focused on a single measurement type.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eFrequency ceiling steps the price tier across the family. Within the combination analyzer line, the N9913A (4 GHz) through N9918A (26.5 GHz) cover the cellular, WiFi, and lower microwave bands; the N9950A through N9952A extend coverage through 50 GHz for millimeter-wave-adjacent applications. The N995xA models also offer broader spectrum analyzer measurement range, with a 9 kHz starting frequency versus 100 kHz on the N991xA.

The FieldFox family covers frequency ranges from 4 GHz through 54 GHz across multiple model variants, and each unit is built to withstand harsh working conditions while delivering measurement performance the datasheet positions as correlating with high-performance benchtop instruments. The instrument is intended as a field-capable platform for measuring cables, antennas, filters, amplifiers, and modulated RF signals.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eFieldFox is positioned by the datasheet for cable and antenna test on cellular and microwave infrastructure, 5G deployment and field testing, satellite and radar coverage verification, beamforming verification with phased array antennas, radar and electronic warfare systems diagnostics, and field signal monitoring with wideband IQ capture. The datasheet specifically identifies hardware installation and maintenance, over-the-air signal quality verification, interference hunting, and characterization of pulsed RF signals as application areas the instrument is designed to address.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eValueTronics stocks and tests the FieldFox handheld analyzer family at our 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every unit we list passes through our in-house performance verification process before shipping, and our condition reports document what our technicians measured rather than what a prior seller described. We have been supplying test and measurement instruments to engineering teams, defense programs, university labs, and field service operations since 1992, and our breadth across more than 120 manufacturers means we can pair a FieldFox with the cables, calibration kits, antennas, and companion instruments a complete field measurement setup typically requires.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eBrand Heritage\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eKeysight Technologies was spun off from Agilent Technologies in 2014, and Agilent itself was created in 1999 when Hewlett-Packard separated its test and measurement business from its computing business. The HP–Agilent–Keysight progression means that FieldFox is a direct continuation of the Hewlett-Packard test and measurement engineering legacy, and calibration support, application engineering, and the broader product ecosystem are now provided under the Keysight name.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eCompare Other Models in This Series\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe FieldFox family is organized into two parallel product lines that share the same handheld chassis and user interface. Combination analyzer models — covering Cable and Antenna Test, Vector Network Analysis, and Spectrum Analysis — use model numbers in the N991x, N993x, N995x, and N912C ranges. Dedicated Spectrum Analyzer models use model numbers in the N993x, N996x, and corresponding C-series ranges. Both lines span frequency coverage from 4 GHz through 54 GHz, allowing a buyer to match the instrument's frequency ceiling to the highest frequency the application requires.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eAcross the family, the datasheet identifies three series generations: the legacy B-Series (now discontinued for several models and replaced by the C-Series equivalents), the current C-Series, and the newly introduced D-Series. The D-Series adds 120 MHz IQ streaming bandwidth, a Linux operating system, SFP+ 10-Gigabit Ethernet interfaces, a touchscreen for file management, and an enhanced DC power supply output. The C-Series N9912C in particular is positioned as a fully software-defined analyzer whose frequency coverage and instrument personality (CAT, VNA, or SA) are selected at purchase and upgradable by software license.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eEach FieldFox model on this page is its own product listing with condition-matched pricing. Every new FieldFox unit is selected and prepared per the condition standards described on the listing, and the model variants in the comparison table below reflect the different frequency ceilings and feature sets available across the family.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe most consequential difference between FieldFox models is the maximum frequency. The N991x and N993x combination and spectrum analyzer models cover up to 4, 6.5, 9, 10, 14, 18, and 26.5 GHz. The N995x and N996x models extend coverage to 32, 44, 50, and 54 GHz, with the highest-frequency 54 GHz models (N9953 and N9963) using 1.85 mm test port connectors. The 26.5 GHz N9918 and N9938 models, and the 32 GHz and above models, use 2.4 mm or 1.85 mm connectors; lower-frequency models in the family use Type-N (female) or 3.5 mm (male) test ports as printed on each model's port labeling.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eBeyond frequency coverage, models differ in their base instrument personality. Combination analyzers (N991x, N993x, N995x at the top of each frequency tier) include CAT and VNA capability as the base function with spectrum analysis available as an option. Dedicated spectrum analyzer models (N993x, N996x in the lower row of each frequency tier) include spectrum analysis as the base function and do not include the full VNA personality, although Option 320 provides reflection measurements including return loss and VSWR. The C-Series N9912C uniquely allows the buyer to choose CAT, NA, and\/or SA personalities at the time of purchase through the CA, NA, and SA option codes, with frequency upgrade available via the N9912CU upgrade product.\u003c\/p\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eModel\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eMax Frequency\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eType\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSeries\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e\u003cstrong\u003eN9953B\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e54 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eB-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9912C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 \/ 6.5 \/ 10 GHz (configurable)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer (Software-Defined)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9913C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9914C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e6.5 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp style=\"margin:0 0 8px 0; font-size:14px; color:#555;\"\u003eAdditional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eProduct Core \u0026amp; Specifications\u003c\/h2\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eGeneral — Physical\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e7.5 lb.

The FieldFox family spans nine frequency ceilings from 4 GHz through 50 GHz, with three primary product lines: combination analyzers (N991xA, N995xA series) that integrate Cable and Antenna Test, Vector Network Analyzer, and Spectrum Analyzer functions; dedicated microwave VNAs (N992xA series); and dedicated microwave spectrum analyzers (N993xA, N996xA series). All FieldFox units share a common platform with a 6.5-inch transflective color LCD-LED backlit display sized for outdoor visibility.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eFieldFox analyzers are used for cable and antenna testing including distance-to-fault measurements, return loss, and VSWR characterization on transmission lines; vector network analysis with full S-parameter measurement (S11, S21, S22, S12) on RF components; spectrum analysis from 9 kHz (on N995xA\/N996xA models) or 100 kHz (on N991xA\/N993xA models) through the instrument's maximum frequency; and a range of specialized measurements available through licensed options including real-time spectrum analysis, I\/Q analysis, noise figure characterization, vector voltmeter operation, pulse measurements with external USB power sensors, and Over-the-Air cellular measurements (LTE FDD, 5GTF).\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eBrand Heritage\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe FieldFox product line is a Keysight Technologies platform. Keysight's test and measurement business traces its lineage to Hewlett-Packard's instrument division, which was spun off as Agilent Technologies in 1999, with the electronic measurement business subsequently separated as Keysight Technologies in 2014. FieldFox analyzers reflect this engineering heritage in their calibration architecture, which is based on the same calibration engine used in Keysight's PNA family of bench network analyzers.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eCompare Other Models in This Series\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe FieldFox family is organized into three product groupings sharing a common handheld platform. The N991xA combination analyzers (N9913A through N9918A) cover 30 kHz to frequency ceilings of 4, 6.5, 9, 14, 18, and 26.5 GHz, integrating Cable and Antenna Test, Vector Network Analyzer, and Spectrum Analyzer functions in a single unit. The N995xA combination analyzers (N9950A, N9951A, N9952A) extend the same combination architecture upward to 32, 44, and 50 GHz with a starting frequency of 300 kHz (CAT\/VNA) or 9 kHz (Spectrum Analyzer).\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eTwo specialized product lines address users whose application is dedicated to a single measurement domain. The N992xA microwave VNAs (N9925A through N9928A) are dedicated vector network analyzers covering 30 kHz through 9, 14, 18, and 26.5 GHz. The N993xA microwave spectrum analyzers (N9935A through N9938A) and N996xA microwave spectrum analyzers (N9960A, N9961A, N9962A) are dedicated spectrum analyzers covering the same frequency tiers as their combination-analyzer counterparts.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eEach model below is its own dedicated product page with new-matched pricing.

Combination analyzer models (N991xA, N995xA) support CAT, VNA, and Spectrum Analyzer measurements on a single unit, making them suitable for users who need multiple measurement domains in one instrument. Dedicated VNA models (N992xA) and dedicated Spectrum Analyzer models (N993xA, N996xA) are configured for users whose application is focused on a single measurement type.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eFrequency ceiling steps the price tier across the family. Within the combination analyzer line, the N9913A (4 GHz) through N9918A (26.5 GHz) cover the cellular, WiFi, and lower microwave bands; the N9950A through N9952A extend coverage through 50 GHz for millimeter-wave-adjacent applications. The N995xA models also offer broader spectrum analyzer measurement range, with a 9 kHz starting frequency versus 100 kHz on the N991xA.

Keysight's test and measurement business traces its lineage to Hewlett-Packard's instrument division, which was spun off as Agilent Technologies in 1999, with the electronic measurement business subsequently separated as Keysight Technologies in 2014. FieldFox analyzers reflect this engineering heritage in their calibration architecture, which is based on the same calibration engine used in Keysight's PNA family of bench network analyzers.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eCompare Other Models in This Series\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe FieldFox family is organized into three product groupings sharing a common handheld platform. The N991xA combination analyzers (N9913A through N9918A) cover 30 kHz to frequency ceilings of 4, 6.5, 9, 14, 18, and 26.5 GHz, integrating Cable and Antenna Test, Vector Network Analyzer, and Spectrum Analyzer functions in a single unit. The N995xA combination analyzers (N9950A, N9951A, N9952A) extend the same combination architecture upward to 32, 44, and 50 GHz with a starting frequency of 300 kHz (CAT\/VNA) or 9 kHz (Spectrum Analyzer).\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eTwo specialized product lines address users whose application is dedicated to a single measurement domain. The N992xA microwave VNAs (N9925A through N9928A) are dedicated vector network analyzers covering 30 kHz through 9, 14, 18, and 26.5 GHz. The N993xA microwave spectrum analyzers (N9935A through N9938A) and N996xA microwave spectrum analyzers (N9960A, N9961A, N9962A) are dedicated spectrum analyzers covering the same frequency tiers as their combination-analyzer counterparts.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eEach model below is its own dedicated product page with new-matched pricing.

Combination analyzer models (N991xA, N995xA) support CAT, VNA, and Spectrum Analyzer measurements on a single unit, making them suitable for users who need multiple measurement domains in one instrument. Dedicated VNA models (N992xA) and dedicated Spectrum Analyzer models (N993xA, N996xA) are configured for users whose application is focused on a single measurement type.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eFrequency ceiling steps the price tier across the family. Within the combination analyzer line, the N9913A (4 GHz) through N9918A (26.5 GHz) cover the cellular, WiFi, and lower microwave bands; the N9950A through N9952A extend coverage through 50 GHz for millimeter-wave-adjacent applications. The N995xA models also offer broader spectrum analyzer measurement range, with a 9 kHz starting frequency versus 100 kHz on the N991xA.

The FieldFox family covers frequency ranges from 4 GHz through 54 GHz across multiple model variants, and each unit is built to withstand harsh working conditions while delivering measurement performance the datasheet positions as correlating with high-performance benchtop instruments. The instrument is intended as a field-capable platform for measuring cables, antennas, filters, amplifiers, and modulated RF signals.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eFieldFox is positioned by the datasheet for cable and antenna test on cellular and microwave infrastructure, 5G deployment and field testing, satellite and radar coverage verification, beamforming verification with phased array antennas, radar and electronic warfare systems diagnostics, and field signal monitoring with wideband IQ capture. The datasheet specifically identifies hardware installation and maintenance, over-the-air signal quality verification, interference hunting, and characterization of pulsed RF signals as application areas the instrument is designed to address.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eValueTronics stocks and tests the FieldFox handheld analyzer family at our 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every unit we list passes through our in-house performance verification process before shipping, and our condition reports document what our technicians measured rather than what a prior seller described. We have been supplying test and measurement instruments to engineering teams, defense programs, university labs, and field service operations since 1992, and our breadth across more than 120 manufacturers means we can pair a FieldFox with the cables, calibration kits, antennas, and companion instruments a complete field measurement setup typically requires.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eBrand Heritage\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eKeysight Technologies was spun off from Agilent Technologies in 2014, and Agilent itself was created in 1999 when Hewlett-Packard separated its test and measurement business from its computing business. The HP–Agilent–Keysight progression means that FieldFox is a direct continuation of the Hewlett-Packard test and measurement engineering legacy, and calibration support, application engineering, and the broader product ecosystem are now provided under the Keysight name.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eCompare Other Models in This Series\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe FieldFox family is organized into two parallel product lines that share the same handheld chassis and user interface. Combination analyzer models — covering Cable and Antenna Test, Vector Network Analysis, and Spectrum Analysis — use model numbers in the N991x, N993x, N995x, and N912C ranges. Dedicated Spectrum Analyzer models use model numbers in the N993x, N996x, and corresponding C-series ranges. Both lines span frequency coverage from 4 GHz through 54 GHz, allowing a buyer to match the instrument's frequency ceiling to the highest frequency the application requires.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eAcross the family, the datasheet identifies three series generations: the legacy B-Series (now discontinued for several models and replaced by the C-Series equivalents), the current C-Series, and the newly introduced D-Series. The D-Series adds 120 MHz IQ streaming bandwidth, a Linux operating system, SFP+ 10-Gigabit Ethernet interfaces, a touchscreen for file management, and an enhanced DC power supply output. The C-Series N9912C in particular is positioned as a fully software-defined analyzer whose frequency coverage and instrument personality (CAT, VNA, or SA) are selected at purchase and upgradable by software license.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eEach FieldFox model on this page is its own product listing with condition-matched pricing. Every new FieldFox unit is selected and prepared per the condition standards described on the listing, and the model variants in the comparison table below reflect the different frequency ceilings and feature sets available across the family.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe most consequential difference between FieldFox models is the maximum frequency. The N991x and N993x combination and spectrum analyzer models cover up to 4, 6.5, 9, 10, 14, 18, and 26.5 GHz. The N995x and N996x models extend coverage to 32, 44, 50, and 54 GHz, with the highest-frequency 54 GHz models (N9953 and N9963) using 1.85 mm test port connectors. The 26.5 GHz N9918 and N9938 models, and the 32 GHz and above models, use 2.4 mm or 1.85 mm connectors; lower-frequency models in the family use Type-N (female) or 3.5 mm (male) test ports as printed on each model's port labeling.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eBeyond frequency coverage, models differ in their base instrument personality. Combination analyzers (N991x, N993x, N995x at the top of each frequency tier) include CAT and VNA capability as the base function with spectrum analysis available as an option. Dedicated spectrum analyzer models (N993x, N996x in the lower row of each frequency tier) include spectrum analysis as the base function and do not include the full VNA personality, although Option 320 provides reflection measurements including return loss and VSWR. The C-Series N9912C uniquely allows the buyer to choose CAT, NA, and\/or SA personalities at the time of purchase through the CA, NA, and SA option codes, with frequency upgrade available via the N9912CU upgrade product.\u003c\/p\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eModel\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eMax Frequency\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eType\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSeries\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e\u003cstrong\u003eN9916D\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e14 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eD-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9912C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 \/ 6.5 \/ 10 GHz (configurable)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer (Software-Defined)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9913C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9914C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e6.5 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp style=\"margin:0 0 8px 0; font-size:14px; color:#555;\"\u003eAdditional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eProduct Core \u0026amp; Specifications\u003c\/h2\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eGeneral — Physical\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e7.5 lb.

The FieldFox family covers frequency ranges from 4 GHz through 54 GHz across multiple model variants, and each unit is built to withstand harsh working conditions while delivering measurement performance the datasheet positions as correlating with high-performance benchtop instruments. The instrument is intended as a field-capable platform for measuring cables, antennas, filters, amplifiers, and modulated RF signals.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eFieldFox is positioned by the datasheet for cable and antenna test on cellular and microwave infrastructure, 5G deployment and field testing, satellite and radar coverage verification, beamforming verification with phased array antennas, radar and electronic warfare systems diagnostics, and field signal monitoring with wideband IQ capture. The datasheet specifically identifies hardware installation and maintenance, over-the-air signal quality verification, interference hunting, and characterization of pulsed RF signals as application areas the instrument is designed to address.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eValueTronics stocks and tests the FieldFox handheld analyzer family at our 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every unit we list passes through our in-house performance verification process before shipping, and our condition reports document what our technicians measured rather than what a prior seller described. We have been supplying test and measurement instruments to engineering teams, defense programs, university labs, and field service operations since 1992, and our breadth across more than 120 manufacturers means we can pair a FieldFox with the cables, calibration kits, antennas, and companion instruments a complete field measurement setup typically requires.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eBrand Heritage\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eKeysight Technologies was spun off from Agilent Technologies in 2014, and Agilent itself was created in 1999 when Hewlett-Packard separated its test and measurement business from its computing business. The HP–Agilent–Keysight progression means that FieldFox is a direct continuation of the Hewlett-Packard test and measurement engineering legacy, and calibration support, application engineering, and the broader product ecosystem are now provided under the Keysight name.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eCompare Other Models in This Series\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe FieldFox family is organized into two parallel product lines that share the same handheld chassis and user interface. Combination analyzer models — covering Cable and Antenna Test, Vector Network Analysis, and Spectrum Analysis — use model numbers in the N991x, N993x, N995x, and N912C ranges. Dedicated Spectrum Analyzer models use model numbers in the N993x, N996x, and corresponding C-series ranges. Both lines span frequency coverage from 4 GHz through 54 GHz, allowing a buyer to match the instrument's frequency ceiling to the highest frequency the application requires.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eAcross the family, the datasheet identifies three series generations: the legacy B-Series (now discontinued for several models and replaced by the C-Series equivalents), the current C-Series, and the newly introduced D-Series. The D-Series adds 120 MHz IQ streaming bandwidth, a Linux operating system, SFP+ 10-Gigabit Ethernet interfaces, a touchscreen for file management, and an enhanced DC power supply output. The C-Series N9912C in particular is positioned as a fully software-defined analyzer whose frequency coverage and instrument personality (CAT, VNA, or SA) are selected at purchase and upgradable by software license.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eEach FieldFox model on this page is its own product listing with condition-matched pricing. Every new FieldFox unit is selected and prepared per the condition standards described on the listing, and the model variants in the comparison table below reflect the different frequency ceilings and feature sets available across the family.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe most consequential difference between FieldFox models is the maximum frequency. The N991x and N993x combination and spectrum analyzer models cover up to 4, 6.5, 9, 10, 14, 18, and 26.5 GHz. The N995x and N996x models extend coverage to 32, 44, 50, and 54 GHz, with the highest-frequency 54 GHz models (N9953 and N9963) using 1.85 mm test port connectors. The 26.5 GHz N9918 and N9938 models, and the 32 GHz and above models, use 2.4 mm or 1.85 mm connectors; lower-frequency models in the family use Type-N (female) or 3.5 mm (male) test ports as printed on each model's port labeling.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eBeyond frequency coverage, models differ in their base instrument personality. Combination analyzers (N991x, N993x, N995x at the top of each frequency tier) include CAT and VNA capability as the base function with spectrum analysis available as an option. Dedicated spectrum analyzer models (N993x, N996x in the lower row of each frequency tier) include spectrum analysis as the base function and do not include the full VNA personality, although Option 320 provides reflection measurements including return loss and VSWR. The C-Series N9912C uniquely allows the buyer to choose CAT, NA, and\/or SA personalities at the time of purchase through the CA, NA, and SA option codes, with frequency upgrade available via the N9912CU upgrade product.\u003c\/p\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eModel\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eMax Frequency\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eType\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSeries\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e\u003cstrong\u003eN9917D\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e18 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eD-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9912C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 \/ 6.5 \/ 10 GHz (configurable)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer (Software-Defined)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9913C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9914C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e6.5 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp style=\"margin:0 0 8px 0; font-size:14px; color:#555;\"\u003eAdditional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eProduct Core \u0026amp; Specifications\u003c\/h2\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eGeneral — Physical\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e7.5 lb.

The FieldFox family covers frequency ranges from 4 GHz through 54 GHz across multiple model variants, and each unit is built to withstand harsh working conditions while delivering measurement performance the datasheet positions as correlating with high-performance benchtop instruments. The instrument is intended as a field-capable platform for measuring cables, antennas, filters, amplifiers, and modulated RF signals.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eFieldFox is positioned by the datasheet for cable and antenna test on cellular and microwave infrastructure, 5G deployment and field testing, satellite and radar coverage verification, beamforming verification with phased array antennas, radar and electronic warfare systems diagnostics, and field signal monitoring with wideband IQ capture. The datasheet specifically identifies hardware installation and maintenance, over-the-air signal quality verification, interference hunting, and characterization of pulsed RF signals as application areas the instrument is designed to address.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eValueTronics stocks and tests the FieldFox handheld analyzer family at our 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every unit we list passes through our in-house performance verification process before shipping, and our condition reports document what our technicians measured rather than what a prior seller described. We have been supplying test and measurement instruments to engineering teams, defense programs, university labs, and field service operations since 1992, and our breadth across more than 120 manufacturers means we can pair a FieldFox with the cables, calibration kits, antennas, and companion instruments a complete field measurement setup typically requires.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eBrand Heritage\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eKeysight Technologies was spun off from Agilent Technologies in 2014, and Agilent itself was created in 1999 when Hewlett-Packard separated its test and measurement business from its computing business. The HP–Agilent–Keysight progression means that FieldFox is a direct continuation of the Hewlett-Packard test and measurement engineering legacy, and calibration support, application engineering, and the broader product ecosystem are now provided under the Keysight name.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eCompare Other Models in This Series\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe FieldFox family is organized into two parallel product lines that share the same handheld chassis and user interface. Combination analyzer models — covering Cable and Antenna Test, Vector Network Analysis, and Spectrum Analysis — use model numbers in the N991x, N993x, N995x, and N912C ranges. Dedicated Spectrum Analyzer models use model numbers in the N993x, N996x, and corresponding C-series ranges. Both lines span frequency coverage from 4 GHz through 54 GHz, allowing a buyer to match the instrument's frequency ceiling to the highest frequency the application requires.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eAcross the family, the datasheet identifies three series generations: the legacy B-Series (now discontinued for several models and replaced by the C-Series equivalents), the current C-Series, and the newly introduced D-Series. The D-Series adds 120 MHz IQ streaming bandwidth, a Linux operating system, SFP+ 10-Gigabit Ethernet interfaces, a touchscreen for file management, and an enhanced DC power supply output. The C-Series N9912C in particular is positioned as a fully software-defined analyzer whose frequency coverage and instrument personality (CAT, VNA, or SA) are selected at purchase and upgradable by software license.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eEach FieldFox model on this page is its own product listing with condition-matched pricing. Every new FieldFox unit is selected and prepared per the condition standards described on the listing, and the model variants in the comparison table below reflect the different frequency ceilings and feature sets available across the family.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe most consequential difference between FieldFox models is the maximum frequency. The N991x and N993x combination and spectrum analyzer models cover up to 4, 6.5, 9, 10, 14, 18, and 26.5 GHz. The N995x and N996x models extend coverage to 32, 44, 50, and 54 GHz, with the highest-frequency 54 GHz models (N9953 and N9963) using 1.85 mm test port connectors. The 26.5 GHz N9918 and N9938 models, and the 32 GHz and above models, use 2.4 mm or 1.85 mm connectors; lower-frequency models in the family use Type-N (female) or 3.5 mm (male) test ports as printed on each model's port labeling.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eBeyond frequency coverage, models differ in their base instrument personality. Combination analyzers (N991x, N993x, N995x at the top of each frequency tier) include CAT and VNA capability as the base function with spectrum analysis available as an option. Dedicated spectrum analyzer models (N993x, N996x in the lower row of each frequency tier) include spectrum analysis as the base function and do not include the full VNA personality, although Option 320 provides reflection measurements including return loss and VSWR. The C-Series N9912C uniquely allows the buyer to choose CAT, NA, and\/or SA personalities at the time of purchase through the CA, NA, and SA option codes, with frequency upgrade available via the N9912CU upgrade product.\u003c\/p\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eModel\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eMax Frequency\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eType\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSeries\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e\u003cstrong\u003eN9918D\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e26.5 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eD-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9912C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 \/ 6.5 \/ 10 GHz (configurable)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer (Software-Defined)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9913C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9914C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e6.5 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp style=\"margin:0 0 8px 0; font-size:14px; color:#555;\"\u003eAdditional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eProduct Core \u0026amp; Specifications\u003c\/h2\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eGeneral — Physical\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e7.5 lb.

The FieldFox family covers frequency ranges from 4 GHz through 54 GHz across multiple model variants, and each unit is built to withstand harsh working conditions while delivering measurement performance the datasheet positions as correlating with high-performance benchtop instruments. The instrument is intended as a field-capable platform for measuring cables, antennas, filters, amplifiers, and modulated RF signals.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eFieldFox is positioned by the datasheet for cable and antenna test on cellular and microwave infrastructure, 5G deployment and field testing, satellite and radar coverage verification, beamforming verification with phased array antennas, radar and electronic warfare systems diagnostics, and field signal monitoring with wideband IQ capture. The datasheet specifically identifies hardware installation and maintenance, over-the-air signal quality verification, interference hunting, and characterization of pulsed RF signals as application areas the instrument is designed to address.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eValueTronics stocks and tests the FieldFox handheld analyzer family at our 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every unit we list passes through our in-house performance verification process before shipping, and our condition reports document what our technicians measured rather than what a prior seller described. We have been supplying test and measurement instruments to engineering teams, defense programs, university labs, and field service operations since 1992, and our breadth across more than 120 manufacturers means we can pair a FieldFox with the cables, calibration kits, antennas, and companion instruments a complete field measurement setup typically requires.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eBrand Heritage\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eKeysight Technologies was spun off from Agilent Technologies in 2014, and Agilent itself was created in 1999 when Hewlett-Packard separated its test and measurement business from its computing business. The HP–Agilent–Keysight progression means that FieldFox is a direct continuation of the Hewlett-Packard test and measurement engineering legacy, and calibration support, application engineering, and the broader product ecosystem are now provided under the Keysight name.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eCompare Other Models in This Series\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe FieldFox family is organized into two parallel product lines that share the same handheld chassis and user interface. Combination analyzer models — covering Cable and Antenna Test, Vector Network Analysis, and Spectrum Analysis — use model numbers in the N991x, N993x, N995x, and N912C ranges. Dedicated Spectrum Analyzer models use model numbers in the N993x, N996x, and corresponding C-series ranges. Both lines span frequency coverage from 4 GHz through 54 GHz, allowing a buyer to match the instrument's frequency ceiling to the highest frequency the application requires.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eAcross the family, the datasheet identifies three series generations: the legacy B-Series (now discontinued for several models and replaced by the C-Series equivalents), the current C-Series, and the newly introduced D-Series. The D-Series adds 120 MHz IQ streaming bandwidth, a Linux operating system, SFP+ 10-Gigabit Ethernet interfaces, a touchscreen for file management, and an enhanced DC power supply output. The C-Series N9912C in particular is positioned as a fully software-defined analyzer whose frequency coverage and instrument personality (CAT, VNA, or SA) are selected at purchase and upgradable by software license.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eEach FieldFox model on this page is its own product listing with condition-matched pricing. Every new FieldFox unit is selected and prepared per the condition standards described on the listing, and the model variants in the comparison table below reflect the different frequency ceilings and feature sets available across the family.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe most consequential difference between FieldFox models is the maximum frequency. The N991x and N993x combination and spectrum analyzer models cover up to 4, 6.5, 9, 10, 14, 18, and 26.5 GHz. The N995x and N996x models extend coverage to 32, 44, 50, and 54 GHz, with the highest-frequency 54 GHz models (N9953 and N9963) using 1.85 mm test port connectors. The 26.5 GHz N9918 and N9938 models, and the 32 GHz and above models, use 2.4 mm or 1.85 mm connectors; lower-frequency models in the family use Type-N (female) or 3.5 mm (male) test ports as printed on each model's port labeling.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eBeyond frequency coverage, models differ in their base instrument personality. Combination analyzers (N991x, N993x, N995x at the top of each frequency tier) include CAT and VNA capability as the base function with spectrum analysis available as an option. Dedicated spectrum analyzer models (N993x, N996x in the lower row of each frequency tier) include spectrum analysis as the base function and do not include the full VNA personality, although Option 320 provides reflection measurements including return loss and VSWR. The C-Series N9912C uniquely allows the buyer to choose CAT, NA, and\/or SA personalities at the time of purchase through the CA, NA, and SA option codes, with frequency upgrade available via the N9912CU upgrade product.\u003c\/p\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eModel\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eMax Frequency\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eType\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSeries\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e\u003cstrong\u003eN9936D\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e14 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eSpectrum Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eD-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9912C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 \/ 6.5 \/ 10 GHz (configurable)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer (Software-Defined)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9913C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9914C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e6.5 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp style=\"margin:0 0 8px 0; font-size:14px; color:#555;\"\u003eAdditional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eProduct Core \u0026amp; Specifications\u003c\/h2\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eGeneral — Physical\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e7.5 lb.

The FieldFox family covers frequency ranges from 4 GHz through 54 GHz across multiple model variants, and each unit is built to withstand harsh working conditions while delivering measurement performance the datasheet positions as correlating with high-performance benchtop instruments. The instrument is intended as a field-capable platform for measuring cables, antennas, filters, amplifiers, and modulated RF signals.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eFieldFox is positioned by the datasheet for cable and antenna test on cellular and microwave infrastructure, 5G deployment and field testing, satellite and radar coverage verification, beamforming verification with phased array antennas, radar and electronic warfare systems diagnostics, and field signal monitoring with wideband IQ capture. The datasheet specifically identifies hardware installation and maintenance, over-the-air signal quality verification, interference hunting, and characterization of pulsed RF signals as application areas the instrument is designed to address.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eValueTronics stocks and tests the FieldFox handheld analyzer family at our 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every unit we list passes through our in-house performance verification process before shipping, and our condition reports document what our technicians measured rather than what a prior seller described. We have been supplying test and measurement instruments to engineering teams, defense programs, university labs, and field service operations since 1992, and our breadth across more than 120 manufacturers means we can pair a FieldFox with the cables, calibration kits, antennas, and companion instruments a complete field measurement setup typically requires.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eBrand Heritage\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eKeysight Technologies was spun off from Agilent Technologies in 2014, and Agilent itself was created in 1999 when Hewlett-Packard separated its test and measurement business from its computing business. The HP–Agilent–Keysight progression means that FieldFox is a direct continuation of the Hewlett-Packard test and measurement engineering legacy, and calibration support, application engineering, and the broader product ecosystem are now provided under the Keysight name.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eCompare Other Models in This Series\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe FieldFox family is organized into two parallel product lines that share the same handheld chassis and user interface. Combination analyzer models — covering Cable and Antenna Test, Vector Network Analysis, and Spectrum Analysis — use model numbers in the N991x, N993x, N995x, and N912C ranges. Dedicated Spectrum Analyzer models use model numbers in the N993x, N996x, and corresponding C-series ranges. Both lines span frequency coverage from 4 GHz through 54 GHz, allowing a buyer to match the instrument's frequency ceiling to the highest frequency the application requires.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eAcross the family, the datasheet identifies three series generations: the legacy B-Series (now discontinued for several models and replaced by the C-Series equivalents), the current C-Series, and the newly introduced D-Series. The D-Series adds 120 MHz IQ streaming bandwidth, a Linux operating system, SFP+ 10-Gigabit Ethernet interfaces, a touchscreen for file management, and an enhanced DC power supply output. The C-Series N9912C in particular is positioned as a fully software-defined analyzer whose frequency coverage and instrument personality (CAT, VNA, or SA) are selected at purchase and upgradable by software license.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eEach FieldFox model on this page is its own product listing with condition-matched pricing. Every new FieldFox unit is selected and prepared per the condition standards described on the listing, and the model variants in the comparison table below reflect the different frequency ceilings and feature sets available across the family.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe most consequential difference between FieldFox models is the maximum frequency. The N991x and N993x combination and spectrum analyzer models cover up to 4, 6.5, 9, 10, 14, 18, and 26.5 GHz. The N995x and N996x models extend coverage to 32, 44, 50, and 54 GHz, with the highest-frequency 54 GHz models (N9953 and N9963) using 1.85 mm test port connectors. The 26.5 GHz N9918 and N9938 models, and the 32 GHz and above models, use 2.4 mm or 1.85 mm connectors; lower-frequency models in the family use Type-N (female) or 3.5 mm (male) test ports as printed on each model's port labeling.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eBeyond frequency coverage, models differ in their base instrument personality. Combination analyzers (N991x, N993x, N995x at the top of each frequency tier) include CAT and VNA capability as the base function with spectrum analysis available as an option. Dedicated spectrum analyzer models (N993x, N996x in the lower row of each frequency tier) include spectrum analysis as the base function and do not include the full VNA personality, although Option 320 provides reflection measurements including return loss and VSWR. The C-Series N9912C uniquely allows the buyer to choose CAT, NA, and\/or SA personalities at the time of purchase through the CA, NA, and SA option codes, with frequency upgrade available via the N9912CU upgrade product.\u003c\/p\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eModel\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eMax Frequency\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eType\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSeries\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e\u003cstrong\u003eN9937D\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e18 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eSpectrum Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eD-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9912C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 \/ 6.5 \/ 10 GHz (configurable)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer (Software-Defined)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9913C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9914C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e6.5 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp style=\"margin:0 0 8px 0; font-size:14px; color:#555;\"\u003eAdditional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eProduct Core \u0026amp; Specifications\u003c\/h2\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eGeneral — Physical\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e7.5 lb.

The FieldFox family covers frequency ranges from 4 GHz through 54 GHz across multiple model variants, and each unit is built to withstand harsh working conditions while delivering measurement performance the datasheet positions as correlating with high-performance benchtop instruments. The instrument is intended as a field-capable platform for measuring cables, antennas, filters, amplifiers, and modulated RF signals.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eFieldFox is positioned by the datasheet for cable and antenna test on cellular and microwave infrastructure, 5G deployment and field testing, satellite and radar coverage verification, beamforming verification with phased array antennas, radar and electronic warfare systems diagnostics, and field signal monitoring with wideband IQ capture. The datasheet specifically identifies hardware installation and maintenance, over-the-air signal quality verification, interference hunting, and characterization of pulsed RF signals as application areas the instrument is designed to address.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eValueTronics stocks and tests the FieldFox handheld analyzer family at our 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every unit we list passes through our in-house performance verification process before shipping, and our condition reports document what our technicians measured rather than what a prior seller described. We have been supplying test and measurement instruments to engineering teams, defense programs, university labs, and field service operations since 1992, and our breadth across more than 120 manufacturers means we can pair a FieldFox with the cables, calibration kits, antennas, and companion instruments a complete field measurement setup typically requires.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eBrand Heritage\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eKeysight Technologies was spun off from Agilent Technologies in 2014, and Agilent itself was created in 1999 when Hewlett-Packard separated its test and measurement business from its computing business. The HP–Agilent–Keysight progression means that FieldFox is a direct continuation of the Hewlett-Packard test and measurement engineering legacy, and calibration support, application engineering, and the broader product ecosystem are now provided under the Keysight name.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eCompare Other Models in This Series\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe FieldFox family is organized into two parallel product lines that share the same handheld chassis and user interface. Combination analyzer models — covering Cable and Antenna Test, Vector Network Analysis, and Spectrum Analysis — use model numbers in the N991x, N993x, N995x, and N912C ranges. Dedicated Spectrum Analyzer models use model numbers in the N993x, N996x, and corresponding C-series ranges. Both lines span frequency coverage from 4 GHz through 54 GHz, allowing a buyer to match the instrument's frequency ceiling to the highest frequency the application requires.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eAcross the family, the datasheet identifies three series generations: the legacy B-Series (now discontinued for several models and replaced by the C-Series equivalents), the current C-Series, and the newly introduced D-Series. The D-Series adds 120 MHz IQ streaming bandwidth, a Linux operating system, SFP+ 10-Gigabit Ethernet interfaces, a touchscreen for file management, and an enhanced DC power supply output. The C-Series N9912C in particular is positioned as a fully software-defined analyzer whose frequency coverage and instrument personality (CAT, VNA, or SA) are selected at purchase and upgradable by software license.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eEach FieldFox model on this page is its own product listing with condition-matched pricing. Every new FieldFox unit is selected and prepared per the condition standards described on the listing, and the model variants in the comparison table below reflect the different frequency ceilings and feature sets available across the family.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe most consequential difference between FieldFox models is the maximum frequency. The N991x and N993x combination and spectrum analyzer models cover up to 4, 6.5, 9, 10, 14, 18, and 26.5 GHz. The N995x and N996x models extend coverage to 32, 44, 50, and 54 GHz, with the highest-frequency 54 GHz models (N9953 and N9963) using 1.85 mm test port connectors. The 26.5 GHz N9918 and N9938 models, and the 32 GHz and above models, use 2.4 mm or 1.85 mm connectors; lower-frequency models in the family use Type-N (female) or 3.5 mm (male) test ports as printed on each model's port labeling.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eBeyond frequency coverage, models differ in their base instrument personality. Combination analyzers (N991x, N993x, N995x at the top of each frequency tier) include CAT and VNA capability as the base function with spectrum analysis available as an option. Dedicated spectrum analyzer models (N993x, N996x in the lower row of each frequency tier) include spectrum analysis as the base function and do not include the full VNA personality, although Option 320 provides reflection measurements including return loss and VSWR. The C-Series N9912C uniquely allows the buyer to choose CAT, NA, and\/or SA personalities at the time of purchase through the CA, NA, and SA option codes, with frequency upgrade available via the N9912CU upgrade product.\u003c\/p\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eModel\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eMax Frequency\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eType\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSeries\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e\u003cstrong\u003eN9938D\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e26.5 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eSpectrum Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eD-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9912C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 \/ 6.5 \/ 10 GHz (configurable)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer (Software-Defined)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9913C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9914C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e6.5 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp style=\"margin:0 0 8px 0; font-size:14px; color:#555;\"\u003eAdditional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eProduct Core \u0026amp; Specifications\u003c\/h2\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eGeneral — Physical\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e7.5 lb.

The FieldFox family covers frequency ranges from 4 GHz through 54 GHz across multiple model variants, and each unit is built to withstand harsh working conditions while delivering measurement performance the datasheet positions as correlating with high-performance benchtop instruments. The instrument is intended as a field-capable platform for measuring cables, antennas, filters, amplifiers, and modulated RF signals.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eFieldFox is positioned by the datasheet for cable and antenna test on cellular and microwave infrastructure, 5G deployment and field testing, satellite and radar coverage verification, beamforming verification with phased array antennas, radar and electronic warfare systems diagnostics, and field signal monitoring with wideband IQ capture. The datasheet specifically identifies hardware installation and maintenance, over-the-air signal quality verification, interference hunting, and characterization of pulsed RF signals as application areas the instrument is designed to address.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eValueTronics stocks and tests the FieldFox handheld analyzer family at our 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every unit we list passes through our in-house performance verification process before shipping, and our condition reports document what our technicians measured rather than what a prior seller described. We have been supplying test and measurement instruments to engineering teams, defense programs, university labs, and field service operations since 1992, and our breadth across more than 120 manufacturers means we can pair a FieldFox with the cables, calibration kits, antennas, and companion instruments a complete field measurement setup typically requires.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eBrand Heritage\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eKeysight Technologies was spun off from Agilent Technologies in 2014, and Agilent itself was created in 1999 when Hewlett-Packard separated its test and measurement business from its computing business. The HP–Agilent–Keysight progression means that FieldFox is a direct continuation of the Hewlett-Packard test and measurement engineering legacy, and calibration support, application engineering, and the broader product ecosystem are now provided under the Keysight name.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eCompare Other Models in This Series\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe FieldFox family is organized into two parallel product lines that share the same handheld chassis and user interface. Combination analyzer models — covering Cable and Antenna Test, Vector Network Analysis, and Spectrum Analysis — use model numbers in the N991x, N993x, N995x, and N912C ranges. Dedicated Spectrum Analyzer models use model numbers in the N993x, N996x, and corresponding C-series ranges. Both lines span frequency coverage from 4 GHz through 54 GHz, allowing a buyer to match the instrument's frequency ceiling to the highest frequency the application requires.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eAcross the family, the datasheet identifies three series generations: the legacy B-Series (now discontinued for several models and replaced by the C-Series equivalents), the current C-Series, and the newly introduced D-Series. The D-Series adds 120 MHz IQ streaming bandwidth, a Linux operating system, SFP+ 10-Gigabit Ethernet interfaces, a touchscreen for file management, and an enhanced DC power supply output. The C-Series N9912C in particular is positioned as a fully software-defined analyzer whose frequency coverage and instrument personality (CAT, VNA, or SA) are selected at purchase and upgradable by software license.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eEach FieldFox model on this page is its own product listing with condition-matched pricing. Every new FieldFox unit is selected and prepared per the condition standards described on the listing, and the model variants in the comparison table below reflect the different frequency ceilings and feature sets available across the family.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe most consequential difference between FieldFox models is the maximum frequency. The N991x and N993x combination and spectrum analyzer models cover up to 4, 6.5, 9, 10, 14, 18, and 26.5 GHz. The N995x and N996x models extend coverage to 32, 44, 50, and 54 GHz, with the highest-frequency 54 GHz models (N9953 and N9963) using 1.85 mm test port connectors. The 26.5 GHz N9918 and N9938 models, and the 32 GHz and above models, use 2.4 mm or 1.85 mm connectors; lower-frequency models in the family use Type-N (female) or 3.5 mm (male) test ports as printed on each model's port labeling.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eBeyond frequency coverage, models differ in their base instrument personality. Combination analyzers (N991x, N993x, N995x at the top of each frequency tier) include CAT and VNA capability as the base function with spectrum analysis available as an option. Dedicated spectrum analyzer models (N993x, N996x in the lower row of each frequency tier) include spectrum analysis as the base function and do not include the full VNA personality, although Option 320 provides reflection measurements including return loss and VSWR. The C-Series N9912C uniquely allows the buyer to choose CAT, NA, and\/or SA personalities at the time of purchase through the CA, NA, and SA option codes, with frequency upgrade available via the N9912CU upgrade product.\u003c\/p\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eModel\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eMax Frequency\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eType\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSeries\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e\u003cstrong\u003eN9950D\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e32 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eD-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9912C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 \/ 6.5 \/ 10 GHz (configurable)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer (Software-Defined)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9913C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9914C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e6.5 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp style=\"margin:0 0 8px 0; font-size:14px; color:#555;\"\u003eAdditional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eProduct Core \u0026amp; Specifications\u003c\/h2\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eGeneral — Physical\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e7.5 lb.

The FieldFox family covers frequency ranges from 4 GHz through 54 GHz across multiple model variants, and each unit is built to withstand harsh working conditions while delivering measurement performance the datasheet positions as correlating with high-performance benchtop instruments. The instrument is intended as a field-capable platform for measuring cables, antennas, filters, amplifiers, and modulated RF signals.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eFieldFox is positioned by the datasheet for cable and antenna test on cellular and microwave infrastructure, 5G deployment and field testing, satellite and radar coverage verification, beamforming verification with phased array antennas, radar and electronic warfare systems diagnostics, and field signal monitoring with wideband IQ capture. The datasheet specifically identifies hardware installation and maintenance, over-the-air signal quality verification, interference hunting, and characterization of pulsed RF signals as application areas the instrument is designed to address.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eValueTronics stocks and tests the FieldFox handheld analyzer family at our 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every unit we list passes through our in-house performance verification process before shipping, and our condition reports document what our technicians measured rather than what a prior seller described. We have been supplying test and measurement instruments to engineering teams, defense programs, university labs, and field service operations since 1992, and our breadth across more than 120 manufacturers means we can pair a FieldFox with the cables, calibration kits, antennas, and companion instruments a complete field measurement setup typically requires.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eBrand Heritage\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eKeysight Technologies was spun off from Agilent Technologies in 2014, and Agilent itself was created in 1999 when Hewlett-Packard separated its test and measurement business from its computing business. The HP–Agilent–Keysight progression means that FieldFox is a direct continuation of the Hewlett-Packard test and measurement engineering legacy, and calibration support, application engineering, and the broader product ecosystem are now provided under the Keysight name.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eCompare Other Models in This Series\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe FieldFox family is organized into two parallel product lines that share the same handheld chassis and user interface. Combination analyzer models — covering Cable and Antenna Test, Vector Network Analysis, and Spectrum Analysis — use model numbers in the N991x, N993x, N995x, and N912C ranges. Dedicated Spectrum Analyzer models use model numbers in the N993x, N996x, and corresponding C-series ranges. Both lines span frequency coverage from 4 GHz through 54 GHz, allowing a buyer to match the instrument's frequency ceiling to the highest frequency the application requires.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eAcross the family, the datasheet identifies three series generations: the legacy B-Series (now discontinued for several models and replaced by the C-Series equivalents), the current C-Series, and the newly introduced D-Series. The D-Series adds 120 MHz IQ streaming bandwidth, a Linux operating system, SFP+ 10-Gigabit Ethernet interfaces, a touchscreen for file management, and an enhanced DC power supply output. The C-Series N9912C in particular is positioned as a fully software-defined analyzer whose frequency coverage and instrument personality (CAT, VNA, or SA) are selected at purchase and upgradable by software license.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eEach FieldFox model on this page is its own product listing with condition-matched pricing. Every new FieldFox unit is selected and prepared per the condition standards described on the listing, and the model variants in the comparison table below reflect the different frequency ceilings and feature sets available across the family.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe most consequential difference between FieldFox models is the maximum frequency. The N991x and N993x combination and spectrum analyzer models cover up to 4, 6.5, 9, 10, 14, 18, and 26.5 GHz. The N995x and N996x models extend coverage to 32, 44, 50, and 54 GHz, with the highest-frequency 54 GHz models (N9953 and N9963) using 1.85 mm test port connectors. The 26.5 GHz N9918 and N9938 models, and the 32 GHz and above models, use 2.4 mm or 1.85 mm connectors; lower-frequency models in the family use Type-N (female) or 3.5 mm (male) test ports as printed on each model's port labeling.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eBeyond frequency coverage, models differ in their base instrument personality. Combination analyzers (N991x, N993x, N995x at the top of each frequency tier) include CAT and VNA capability as the base function with spectrum analysis available as an option. Dedicated spectrum analyzer models (N993x, N996x in the lower row of each frequency tier) include spectrum analysis as the base function and do not include the full VNA personality, although Option 320 provides reflection measurements including return loss and VSWR. The C-Series N9912C uniquely allows the buyer to choose CAT, NA, and\/or SA personalities at the time of purchase through the CA, NA, and SA option codes, with frequency upgrade available via the N9912CU upgrade product.\u003c\/p\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eModel\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eMax Frequency\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eType\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSeries\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e\u003cstrong\u003eN9951D\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e44 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eD-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9912C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 \/ 6.5 \/ 10 GHz (configurable)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer (Software-Defined)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9913C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9914C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e6.5 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp style=\"margin:0 0 8px 0; font-size:14px; color:#555;\"\u003eAdditional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eProduct Core \u0026amp; Specifications\u003c\/h2\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eGeneral — Physical\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e7.5 lb.

The FieldFox family covers frequency ranges from 4 GHz through 54 GHz across multiple model variants, and each unit is built to withstand harsh working conditions while delivering measurement performance the datasheet positions as correlating with high-performance benchtop instruments. The instrument is intended as a field-capable platform for measuring cables, antennas, filters, amplifiers, and modulated RF signals.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eFieldFox is positioned by the datasheet for cable and antenna test on cellular and microwave infrastructure, 5G deployment and field testing, satellite and radar coverage verification, beamforming verification with phased array antennas, radar and electronic warfare systems diagnostics, and field signal monitoring with wideband IQ capture. The datasheet specifically identifies hardware installation and maintenance, over-the-air signal quality verification, interference hunting, and characterization of pulsed RF signals as application areas the instrument is designed to address.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eValueTronics stocks and tests the FieldFox handheld analyzer family at our 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every unit we list passes through our in-house performance verification process before shipping, and our condition reports document what our technicians measured rather than what a prior seller described. We have been supplying test and measurement instruments to engineering teams, defense programs, university labs, and field service operations since 1992, and our breadth across more than 120 manufacturers means we can pair a FieldFox with the cables, calibration kits, antennas, and companion instruments a complete field measurement setup typically requires.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eBrand Heritage\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eKeysight Technologies was spun off from Agilent Technologies in 2014, and Agilent itself was created in 1999 when Hewlett-Packard separated its test and measurement business from its computing business. The HP–Agilent–Keysight progression means that FieldFox is a direct continuation of the Hewlett-Packard test and measurement engineering legacy, and calibration support, application engineering, and the broader product ecosystem are now provided under the Keysight name.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eCompare Other Models in This Series\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe FieldFox family is organized into two parallel product lines that share the same handheld chassis and user interface. Combination analyzer models — covering Cable and Antenna Test, Vector Network Analysis, and Spectrum Analysis — use model numbers in the N991x, N993x, N995x, and N912C ranges. Dedicated Spectrum Analyzer models use model numbers in the N993x, N996x, and corresponding C-series ranges. Both lines span frequency coverage from 4 GHz through 54 GHz, allowing a buyer to match the instrument's frequency ceiling to the highest frequency the application requires.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eAcross the family, the datasheet identifies three series generations: the legacy B-Series (now discontinued for several models and replaced by the C-Series equivalents), the current C-Series, and the newly introduced D-Series. The D-Series adds 120 MHz IQ streaming bandwidth, a Linux operating system, SFP+ 10-Gigabit Ethernet interfaces, a touchscreen for file management, and an enhanced DC power supply output. The C-Series N9912C in particular is positioned as a fully software-defined analyzer whose frequency coverage and instrument personality (CAT, VNA, or SA) are selected at purchase and upgradable by software license.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eEach FieldFox model on this page is its own product listing with condition-matched pricing. Every new FieldFox unit is selected and prepared per the condition standards described on the listing, and the model variants in the comparison table below reflect the different frequency ceilings and feature sets available across the family.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe most consequential difference between FieldFox models is the maximum frequency. The N991x and N993x combination and spectrum analyzer models cover up to 4, 6.5, 9, 10, 14, 18, and 26.5 GHz. The N995x and N996x models extend coverage to 32, 44, 50, and 54 GHz, with the highest-frequency 54 GHz models (N9953 and N9963) using 1.85 mm test port connectors. The 26.5 GHz N9918 and N9938 models, and the 32 GHz and above models, use 2.4 mm or 1.85 mm connectors; lower-frequency models in the family use Type-N (female) or 3.5 mm (male) test ports as printed on each model's port labeling.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eBeyond frequency coverage, models differ in their base instrument personality. Combination analyzers (N991x, N993x, N995x at the top of each frequency tier) include CAT and VNA capability as the base function with spectrum analysis available as an option. Dedicated spectrum analyzer models (N993x, N996x in the lower row of each frequency tier) include spectrum analysis as the base function and do not include the full VNA personality, although Option 320 provides reflection measurements including return loss and VSWR. The C-Series N9912C uniquely allows the buyer to choose CAT, NA, and\/or SA personalities at the time of purchase through the CA, NA, and SA option codes, with frequency upgrade available via the N9912CU upgrade product.\u003c\/p\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eModel\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eMax Frequency\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eType\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSeries\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e\u003cstrong\u003eN9952D\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e50 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eD-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9912C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 \/ 6.5 \/ 10 GHz (configurable)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer (Software-Defined)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9913C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9914C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e6.5 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp style=\"margin:0 0 8px 0; font-size:14px; color:#555;\"\u003eAdditional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eProduct Core \u0026amp; Specifications\u003c\/h2\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eGeneral — Physical\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e7.5 lb.

The FieldFox family covers frequency ranges from 4 GHz through 54 GHz across multiple model variants, and each unit is built to withstand harsh working conditions while delivering measurement performance the datasheet positions as correlating with high-performance benchtop instruments. The instrument is intended as a field-capable platform for measuring cables, antennas, filters, amplifiers, and modulated RF signals.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eFieldFox is positioned by the datasheet for cable and antenna test on cellular and microwave infrastructure, 5G deployment and field testing, satellite and radar coverage verification, beamforming verification with phased array antennas, radar and electronic warfare systems diagnostics, and field signal monitoring with wideband IQ capture. The datasheet specifically identifies hardware installation and maintenance, over-the-air signal quality verification, interference hunting, and characterization of pulsed RF signals as application areas the instrument is designed to address.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eValueTronics stocks and tests the FieldFox handheld analyzer family at our 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every unit we list passes through our in-house performance verification process before shipping, and our condition reports document what our technicians measured rather than what a prior seller described. We have been supplying test and measurement instruments to engineering teams, defense programs, university labs, and field service operations since 1992, and our breadth across more than 120 manufacturers means we can pair a FieldFox with the cables, calibration kits, antennas, and companion instruments a complete field measurement setup typically requires.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eBrand Heritage\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eKeysight Technologies was spun off from Agilent Technologies in 2014, and Agilent itself was created in 1999 when Hewlett-Packard separated its test and measurement business from its computing business. The HP–Agilent–Keysight progression means that FieldFox is a direct continuation of the Hewlett-Packard test and measurement engineering legacy, and calibration support, application engineering, and the broader product ecosystem are now provided under the Keysight name.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eCompare Other Models in This Series\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe FieldFox family is organized into two parallel product lines that share the same handheld chassis and user interface. Combination analyzer models — covering Cable and Antenna Test, Vector Network Analysis, and Spectrum Analysis — use model numbers in the N991x, N993x, N995x, and N912C ranges. Dedicated Spectrum Analyzer models use model numbers in the N993x, N996x, and corresponding C-series ranges. Both lines span frequency coverage from 4 GHz through 54 GHz, allowing a buyer to match the instrument's frequency ceiling to the highest frequency the application requires.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eAcross the family, the datasheet identifies three series generations: the legacy B-Series (now discontinued for several models and replaced by the C-Series equivalents), the current C-Series, and the newly introduced D-Series. The D-Series adds 120 MHz IQ streaming bandwidth, a Linux operating system, SFP+ 10-Gigabit Ethernet interfaces, a touchscreen for file management, and an enhanced DC power supply output. The C-Series N9912C in particular is positioned as a fully software-defined analyzer whose frequency coverage and instrument personality (CAT, VNA, or SA) are selected at purchase and upgradable by software license.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eEach FieldFox model on this page is its own product listing with condition-matched pricing. Every new FieldFox unit is selected and prepared per the condition standards described on the listing, and the model variants in the comparison table below reflect the different frequency ceilings and feature sets available across the family.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe most consequential difference between FieldFox models is the maximum frequency. The N991x and N993x combination and spectrum analyzer models cover up to 4, 6.5, 9, 10, 14, 18, and 26.5 GHz. The N995x and N996x models extend coverage to 32, 44, 50, and 54 GHz, with the highest-frequency 54 GHz models (N9953 and N9963) using 1.85 mm test port connectors. The 26.5 GHz N9918 and N9938 models, and the 32 GHz and above models, use 2.4 mm or 1.85 mm connectors; lower-frequency models in the family use Type-N (female) or 3.5 mm (male) test ports as printed on each model's port labeling.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eBeyond frequency coverage, models differ in their base instrument personality. Combination analyzers (N991x, N993x, N995x at the top of each frequency tier) include CAT and VNA capability as the base function with spectrum analysis available as an option. Dedicated spectrum analyzer models (N993x, N996x in the lower row of each frequency tier) include spectrum analysis as the base function and do not include the full VNA personality, although Option 320 provides reflection measurements including return loss and VSWR. The C-Series N9912C uniquely allows the buyer to choose CAT, NA, and\/or SA personalities at the time of purchase through the CA, NA, and SA option codes, with frequency upgrade available via the N9912CU upgrade product.\u003c\/p\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eModel\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eMax Frequency\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eType\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSeries\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e\u003cstrong\u003eN9953D\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e54 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eD-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9912C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 \/ 6.5 \/ 10 GHz (configurable)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer (Software-Defined)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9913C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9914C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e6.5 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp style=\"margin:0 0 8px 0; font-size:14px; color:#555;\"\u003eAdditional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eProduct Core \u0026amp; Specifications\u003c\/h2\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eGeneral — Physical\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e7.5 lb.

The FieldFox family covers frequency ranges from 4 GHz through 54 GHz across multiple model variants, and each unit is built to withstand harsh working conditions while delivering measurement performance the datasheet positions as correlating with high-performance benchtop instruments. The instrument is intended as a field-capable platform for measuring cables, antennas, filters, amplifiers, and modulated RF signals.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eFieldFox is positioned by the datasheet for cable and antenna test on cellular and microwave infrastructure, 5G deployment and field testing, satellite and radar coverage verification, beamforming verification with phased array antennas, radar and electronic warfare systems diagnostics, and field signal monitoring with wideband IQ capture. The datasheet specifically identifies hardware installation and maintenance, over-the-air signal quality verification, interference hunting, and characterization of pulsed RF signals as application areas the instrument is designed to address.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eValueTronics stocks and tests the FieldFox handheld analyzer family at our 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every unit we list passes through our in-house performance verification process before shipping, and our condition reports document what our technicians measured rather than what a prior seller described. We have been supplying test and measurement instruments to engineering teams, defense programs, university labs, and field service operations since 1992, and our breadth across more than 120 manufacturers means we can pair a FieldFox with the cables, calibration kits, antennas, and companion instruments a complete field measurement setup typically requires.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eBrand Heritage\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eKeysight Technologies was spun off from Agilent Technologies in 2014, and Agilent itself was created in 1999 when Hewlett-Packard separated its test and measurement business from its computing business. The HP–Agilent–Keysight progression means that FieldFox is a direct continuation of the Hewlett-Packard test and measurement engineering legacy, and calibration support, application engineering, and the broader product ecosystem are now provided under the Keysight name.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eCompare Other Models in This Series\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe FieldFox family is organized into two parallel product lines that share the same handheld chassis and user interface. Combination analyzer models — covering Cable and Antenna Test, Vector Network Analysis, and Spectrum Analysis — use model numbers in the N991x, N993x, N995x, and N912C ranges. Dedicated Spectrum Analyzer models use model numbers in the N993x, N996x, and corresponding C-series ranges. Both lines span frequency coverage from 4 GHz through 54 GHz, allowing a buyer to match the instrument's frequency ceiling to the highest frequency the application requires.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eAcross the family, the datasheet identifies three series generations: the legacy B-Series (now discontinued for several models and replaced by the C-Series equivalents), the current C-Series, and the newly introduced D-Series. The D-Series adds 120 MHz IQ streaming bandwidth, a Linux operating system, SFP+ 10-Gigabit Ethernet interfaces, a touchscreen for file management, and an enhanced DC power supply output. The C-Series N9912C in particular is positioned as a fully software-defined analyzer whose frequency coverage and instrument personality (CAT, VNA, or SA) are selected at purchase and upgradable by software license.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eEach FieldFox model on this page is its own product listing with condition-matched pricing. Every new FieldFox unit is selected and prepared per the condition standards described on the listing, and the model variants in the comparison table below reflect the different frequency ceilings and feature sets available across the family.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe most consequential difference between FieldFox models is the maximum frequency. The N991x and N993x combination and spectrum analyzer models cover up to 4, 6.5, 9, 10, 14, 18, and 26.5 GHz. The N995x and N996x models extend coverage to 32, 44, 50, and 54 GHz, with the highest-frequency 54 GHz models (N9953 and N9963) using 1.85 mm test port connectors. The 26.5 GHz N9918 and N9938 models, and the 32 GHz and above models, use 2.4 mm or 1.85 mm connectors; lower-frequency models in the family use Type-N (female) or 3.5 mm (male) test ports as printed on each model's port labeling.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eBeyond frequency coverage, models differ in their base instrument personality. Combination analyzers (N991x, N993x, N995x at the top of each frequency tier) include CAT and VNA capability as the base function with spectrum analysis available as an option. Dedicated spectrum analyzer models (N993x, N996x in the lower row of each frequency tier) include spectrum analysis as the base function and do not include the full VNA personality, although Option 320 provides reflection measurements including return loss and VSWR. The C-Series N9912C uniquely allows the buyer to choose CAT, NA, and\/or SA personalities at the time of purchase through the CA, NA, and SA option codes, with frequency upgrade available via the N9912CU upgrade product.\u003c\/p\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eModel\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eMax Frequency\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eType\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSeries\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e\u003cstrong\u003eN9960D\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e32 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eSpectrum Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eD-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9912C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 \/ 6.5 \/ 10 GHz (configurable)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer (Software-Defined)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9913C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9914C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e6.5 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp style=\"margin:0 0 8px 0; font-size:14px; color:#555;\"\u003eAdditional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eProduct Core \u0026amp; Specifications\u003c\/h2\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eGeneral — Physical\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e7.5 lb.

The FieldFox family covers frequency ranges from 4 GHz through 54 GHz across multiple model variants, and each unit is built to withstand harsh working conditions while delivering measurement performance the datasheet positions as correlating with high-performance benchtop instruments. The instrument is intended as a field-capable platform for measuring cables, antennas, filters, amplifiers, and modulated RF signals.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eFieldFox is positioned by the datasheet for cable and antenna test on cellular and microwave infrastructure, 5G deployment and field testing, satellite and radar coverage verification, beamforming verification with phased array antennas, radar and electronic warfare systems diagnostics, and field signal monitoring with wideband IQ capture. The datasheet specifically identifies hardware installation and maintenance, over-the-air signal quality verification, interference hunting, and characterization of pulsed RF signals as application areas the instrument is designed to address.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eValueTronics stocks and tests the FieldFox handheld analyzer family at our 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every unit we list passes through our in-house performance verification process before shipping, and our condition reports document what our technicians measured rather than what a prior seller described. We have been supplying test and measurement instruments to engineering teams, defense programs, university labs, and field service operations since 1992, and our breadth across more than 120 manufacturers means we can pair a FieldFox with the cables, calibration kits, antennas, and companion instruments a complete field measurement setup typically requires.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eBrand Heritage\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eKeysight Technologies was spun off from Agilent Technologies in 2014, and Agilent itself was created in 1999 when Hewlett-Packard separated its test and measurement business from its computing business. The HP–Agilent–Keysight progression means that FieldFox is a direct continuation of the Hewlett-Packard test and measurement engineering legacy, and calibration support, application engineering, and the broader product ecosystem are now provided under the Keysight name.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eCompare Other Models in This Series\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe FieldFox family is organized into two parallel product lines that share the same handheld chassis and user interface. Combination analyzer models — covering Cable and Antenna Test, Vector Network Analysis, and Spectrum Analysis — use model numbers in the N991x, N993x, N995x, and N912C ranges. Dedicated Spectrum Analyzer models use model numbers in the N993x, N996x, and corresponding C-series ranges. Both lines span frequency coverage from 4 GHz through 54 GHz, allowing a buyer to match the instrument's frequency ceiling to the highest frequency the application requires.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eAcross the family, the datasheet identifies three series generations: the legacy B-Series (now discontinued for several models and replaced by the C-Series equivalents), the current C-Series, and the newly introduced D-Series. The D-Series adds 120 MHz IQ streaming bandwidth, a Linux operating system, SFP+ 10-Gigabit Ethernet interfaces, a touchscreen for file management, and an enhanced DC power supply output. The C-Series N9912C in particular is positioned as a fully software-defined analyzer whose frequency coverage and instrument personality (CAT, VNA, or SA) are selected at purchase and upgradable by software license.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eEach FieldFox model on this page is its own product listing with condition-matched pricing. Every new FieldFox unit is selected and prepared per the condition standards described on the listing, and the model variants in the comparison table below reflect the different frequency ceilings and feature sets available across the family.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe most consequential difference between FieldFox models is the maximum frequency. The N991x and N993x combination and spectrum analyzer models cover up to 4, 6.5, 9, 10, 14, 18, and 26.5 GHz. The N995x and N996x models extend coverage to 32, 44, 50, and 54 GHz, with the highest-frequency 54 GHz models (N9953 and N9963) using 1.85 mm test port connectors. The 26.5 GHz N9918 and N9938 models, and the 32 GHz and above models, use 2.4 mm or 1.85 mm connectors; lower-frequency models in the family use Type-N (female) or 3.5 mm (male) test ports as printed on each model's port labeling.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eBeyond frequency coverage, models differ in their base instrument personality. Combination analyzers (N991x, N993x, N995x at the top of each frequency tier) include CAT and VNA capability as the base function with spectrum analysis available as an option. Dedicated spectrum analyzer models (N993x, N996x in the lower row of each frequency tier) include spectrum analysis as the base function and do not include the full VNA personality, although Option 320 provides reflection measurements including return loss and VSWR. The C-Series N9912C uniquely allows the buyer to choose CAT, NA, and\/or SA personalities at the time of purchase through the CA, NA, and SA option codes, with frequency upgrade available via the N9912CU upgrade product.\u003c\/p\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eModel\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eMax Frequency\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eType\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSeries\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e\u003cstrong\u003eN9961D\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e44 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eSpectrum Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eD-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9912C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 \/ 6.5 \/ 10 GHz (configurable)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer (Software-Defined)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9913C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9914C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e6.5 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp style=\"margin:0 0 8px 0; font-size:14px; color:#555;\"\u003eAdditional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eProduct Core \u0026amp; Specifications\u003c\/h2\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eGeneral — Physical\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e7.5 lb.

The FieldFox family covers frequency ranges from 4 GHz through 54 GHz across multiple model variants, and each unit is built to withstand harsh working conditions while delivering measurement performance the datasheet positions as correlating with high-performance benchtop instruments. The instrument is intended as a field-capable platform for measuring cables, antennas, filters, amplifiers, and modulated RF signals.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eFieldFox is positioned by the datasheet for cable and antenna test on cellular and microwave infrastructure, 5G deployment and field testing, satellite and radar coverage verification, beamforming verification with phased array antennas, radar and electronic warfare systems diagnostics, and field signal monitoring with wideband IQ capture. The datasheet specifically identifies hardware installation and maintenance, over-the-air signal quality verification, interference hunting, and characterization of pulsed RF signals as application areas the instrument is designed to address.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eValueTronics stocks and tests the FieldFox handheld analyzer family at our 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every unit we list passes through our in-house performance verification process before shipping, and our condition reports document what our technicians measured rather than what a prior seller described. We have been supplying test and measurement instruments to engineering teams, defense programs, university labs, and field service operations since 1992, and our breadth across more than 120 manufacturers means we can pair a FieldFox with the cables, calibration kits, antennas, and companion instruments a complete field measurement setup typically requires.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eBrand Heritage\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eKeysight Technologies was spun off from Agilent Technologies in 2014, and Agilent itself was created in 1999 when Hewlett-Packard separated its test and measurement business from its computing business. The HP–Agilent–Keysight progression means that FieldFox is a direct continuation of the Hewlett-Packard test and measurement engineering legacy, and calibration support, application engineering, and the broader product ecosystem are now provided under the Keysight name.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eCompare Other Models in This Series\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe FieldFox family is organized into two parallel product lines that share the same handheld chassis and user interface. Combination analyzer models — covering Cable and Antenna Test, Vector Network Analysis, and Spectrum Analysis — use model numbers in the N991x, N993x, N995x, and N912C ranges. Dedicated Spectrum Analyzer models use model numbers in the N993x, N996x, and corresponding C-series ranges. Both lines span frequency coverage from 4 GHz through 54 GHz, allowing a buyer to match the instrument's frequency ceiling to the highest frequency the application requires.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eAcross the family, the datasheet identifies three series generations: the legacy B-Series (now discontinued for several models and replaced by the C-Series equivalents), the current C-Series, and the newly introduced D-Series. The D-Series adds 120 MHz IQ streaming bandwidth, a Linux operating system, SFP+ 10-Gigabit Ethernet interfaces, a touchscreen for file management, and an enhanced DC power supply output. The C-Series N9912C in particular is positioned as a fully software-defined analyzer whose frequency coverage and instrument personality (CAT, VNA, or SA) are selected at purchase and upgradable by software license.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eEach FieldFox model on this page is its own product listing with condition-matched pricing. Every new FieldFox unit is selected and prepared per the condition standards described on the listing, and the model variants in the comparison table below reflect the different frequency ceilings and feature sets available across the family.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe most consequential difference between FieldFox models is the maximum frequency. The N991x and N993x combination and spectrum analyzer models cover up to 4, 6.5, 9, 10, 14, 18, and 26.5 GHz. The N995x and N996x models extend coverage to 32, 44, 50, and 54 GHz, with the highest-frequency 54 GHz models (N9953 and N9963) using 1.85 mm test port connectors. The 26.5 GHz N9918 and N9938 models, and the 32 GHz and above models, use 2.4 mm or 1.85 mm connectors; lower-frequency models in the family use Type-N (female) or 3.5 mm (male) test ports as printed on each model's port labeling.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eBeyond frequency coverage, models differ in their base instrument personality. Combination analyzers (N991x, N993x, N995x at the top of each frequency tier) include CAT and VNA capability as the base function with spectrum analysis available as an option. Dedicated spectrum analyzer models (N993x, N996x in the lower row of each frequency tier) include spectrum analysis as the base function and do not include the full VNA personality, although Option 320 provides reflection measurements including return loss and VSWR. The C-Series N9912C uniquely allows the buyer to choose CAT, NA, and\/or SA personalities at the time of purchase through the CA, NA, and SA option codes, with frequency upgrade available via the N9912CU upgrade product.\u003c\/p\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eModel\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eMax Frequency\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eType\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSeries\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e\u003cstrong\u003eN9962D\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e50 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eSpectrum Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eD-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9912C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 \/ 6.5 \/ 10 GHz (configurable)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer (Software-Defined)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9913C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9914C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e6.5 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp style=\"margin:0 0 8px 0; font-size:14px; color:#555;\"\u003eAdditional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eProduct Core \u0026amp; Specifications\u003c\/h2\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eGeneral — Physical\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e7.5 lb.

The FieldFox family covers frequency ranges from 4 GHz through 54 GHz across multiple model variants, and each unit is built to withstand harsh working conditions while delivering measurement performance the datasheet positions as correlating with high-performance benchtop instruments. The instrument is intended as a field-capable platform for measuring cables, antennas, filters, amplifiers, and modulated RF signals.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eFieldFox is positioned by the datasheet for cable and antenna test on cellular and microwave infrastructure, 5G deployment and field testing, satellite and radar coverage verification, beamforming verification with phased array antennas, radar and electronic warfare systems diagnostics, and field signal monitoring with wideband IQ capture. The datasheet specifically identifies hardware installation and maintenance, over-the-air signal quality verification, interference hunting, and characterization of pulsed RF signals as application areas the instrument is designed to address.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eValueTronics stocks and tests the FieldFox handheld analyzer family at our 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every unit we list passes through our in-house performance verification process before shipping, and our condition reports document what our technicians measured rather than what a prior seller described. We have been supplying test and measurement instruments to engineering teams, defense programs, university labs, and field service operations since 1992, and our breadth across more than 120 manufacturers means we can pair a FieldFox with the cables, calibration kits, antennas, and companion instruments a complete field measurement setup typically requires.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eBrand Heritage\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eKeysight Technologies was spun off from Agilent Technologies in 2014, and Agilent itself was created in 1999 when Hewlett-Packard separated its test and measurement business from its computing business. The HP–Agilent–Keysight progression means that FieldFox is a direct continuation of the Hewlett-Packard test and measurement engineering legacy, and calibration support, application engineering, and the broader product ecosystem are now provided under the Keysight name.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eCompare Other Models in This Series\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe FieldFox family is organized into two parallel product lines that share the same handheld chassis and user interface. Combination analyzer models — covering Cable and Antenna Test, Vector Network Analysis, and Spectrum Analysis — use model numbers in the N991x, N993x, N995x, and N912C ranges. Dedicated Spectrum Analyzer models use model numbers in the N993x, N996x, and corresponding C-series ranges. Both lines span frequency coverage from 4 GHz through 54 GHz, allowing a buyer to match the instrument's frequency ceiling to the highest frequency the application requires.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eAcross the family, the datasheet identifies three series generations: the legacy B-Series (now discontinued for several models and replaced by the C-Series equivalents), the current C-Series, and the newly introduced D-Series. The D-Series adds 120 MHz IQ streaming bandwidth, a Linux operating system, SFP+ 10-Gigabit Ethernet interfaces, a touchscreen for file management, and an enhanced DC power supply output. The C-Series N9912C in particular is positioned as a fully software-defined analyzer whose frequency coverage and instrument personality (CAT, VNA, or SA) are selected at purchase and upgradable by software license.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eEach FieldFox model on this page is its own product listing with condition-matched pricing. Every new FieldFox unit is selected and prepared per the condition standards described on the listing, and the model variants in the comparison table below reflect the different frequency ceilings and feature sets available across the family.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe most consequential difference between FieldFox models is the maximum frequency. The N991x and N993x combination and spectrum analyzer models cover up to 4, 6.5, 9, 10, 14, 18, and 26.5 GHz. The N995x and N996x models extend coverage to 32, 44, 50, and 54 GHz, with the highest-frequency 54 GHz models (N9953 and N9963) using 1.85 mm test port connectors. The 26.5 GHz N9918 and N9938 models, and the 32 GHz and above models, use 2.4 mm or 1.85 mm connectors; lower-frequency models in the family use Type-N (female) or 3.5 mm (male) test ports as printed on each model's port labeling.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eBeyond frequency coverage, models differ in their base instrument personality. Combination analyzers (N991x, N993x, N995x at the top of each frequency tier) include CAT and VNA capability as the base function with spectrum analysis available as an option. Dedicated spectrum analyzer models (N993x, N996x in the lower row of each frequency tier) include spectrum analysis as the base function and do not include the full VNA personality, although Option 320 provides reflection measurements including return loss and VSWR. The C-Series N9912C uniquely allows the buyer to choose CAT, NA, and\/or SA personalities at the time of purchase through the CA, NA, and SA option codes, with frequency upgrade available via the N9912CU upgrade product.\u003c\/p\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eModel\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eMax Frequency\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eType\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSeries\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e\u003cstrong\u003eN9963D\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e54 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eSpectrum Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eD-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9912C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 \/ 6.5 \/ 10 GHz (configurable)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer (Software-Defined)\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9913C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e4 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eN9914C\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e6.5 GHz\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eCombination Analyzer\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eC-Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp style=\"margin:0 0 8px 0; font-size:14px; color:#555;\"\u003eAdditional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eProduct Core \u0026amp; Specifications\u003c\/h2\u003e\u003ctable style=\"border-collapse:collapse; width:100%; clear:both; text-align:left; vertical-align:top; margin:0 0 16px 0;\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003cth style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc; background:#f5f5f5;\"\u003eGeneral — Physical\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px; text-align:left; vertical-align:top; border:1px solid #ccc;\"\u003e7.5 lb.
