The Agilent FieldFox RF Analyzer N9912A is a handheld, multi-function RF analyzer built to test and maintain wireless networks in the field. Positioned as the world's most integrated handheld RF analyzer, it consolidates cable and antenna analysis, spectrum analysis, network analysis, power metering, and vector voltmeter measurement into a single portable instrument, so a technician can carry one tool to a cell site instead of several.
The instrument targets the deployment and maintenance of increasingly complex wireless networks, where operating frequencies have climbed toward 5.8 GHz and service providers must build and maintain more base stations in the same coverage area. Because fifty to sixty percent of cell site problems trace to faulty cables, connectors, and antennas, the FieldFox makes return loss, VSWR, insertion loss/transmission, one-port cable loss, and distance-to-fault measurements to keep feed-line and antenna systems healthy. Its built-in spectrum analysis is aimed at locating internal and external interference, a major source of cell site problems. Listed vector voltmeter applications include cable trimming of phase-matched cables, verifying the isolation of two-port components, and radio navigation work such as VHF omnidirectional radio range (VOR) and instrument landing systems (ILS).
ValueTronics stocks and holds its own inventory in a 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, serving test-and-measurement buyers since 1992. Every used unit is inspected and functionally verified in-house before it ships, while new units ship factory-sealed exactly as received from the manufacturer, so you can order with confidence in either condition.
This instrument carries Agilent Technologies branding. Hewlett-Packard spun out its test-and-measurement business as Agilent Technologies in 1999, and Agilent's electronic measurement business was subsequently established as Keysight Technologies in 2014.

Important: Maximum DC voltage at the RF In and RF Out ports: +/-50 VDC. Maximum input power at the RF In port: +27 dBm (0.5 W).
Important: The N9912A base unit is a one-port 4 GHz cable and antenna analyzer with broadband calibration, CalReady, and standard mechanical cal kit support; spectrum analyzer, transmission measurement, network analysis, power meter, and vector voltmeter functions each require their respective options (104/106, 110, 230/231, 235, 302, 303, 308).
Important: Power meter measurements (Option 302) require an Agilent U2000 Series USB power sensor, which is not included with the base unit and must be ordered separately; the sensor covers 9 kHz to 24 GHz (sensor dependent).
Important: Spectrum analyzer (Option 230/231) start frequency is 100 kHz, usable to 5 kHz.
Important: When an additional device (such as a jumper cable or attenuator) is added to the test port, the instrument must be calibrated using a calibration kit (cal kit).
Recommended pairing: with external USB power sensor support (Option 302), the FieldFox works with the Agilent U2000 Series USB power sensor for true average power measurements up to 24 GHz.
