# Keysight N5227B 900 Hz to 67 GHz 2-Port and 4-Port PNA Network Analyzer (Pre-Owned) # Keysight N5227B 900 Hz to 67 GHz 2-Port and 4-Port PNA Network Analyzer (Pre-Owned) ## Key Features At A Glance - 2-port and 4-port models spanning 10 MHz to 67 GHz; LFE-equipped options extend coverage down to 900 Hz - 1.85 mm (male), 50 Ω test port connectors - 1 Hz frequency resolution with ±0.7 ppm frequency accuracy - LAN 10/100/1000BaseT, dual GPIB (IEEE-488), and USB 2.0 interfaces; LXI Class C for automated test systems - Extended-power-range options add source/receiver attenuators and bias-tees (Options 219, 419, 220, 420) - 12.1 in diagonal active-matrix color LCD at 1280 × 800 resolution - Corrected performance specified with the 85058B calibration kit and N4694A/N4694D ECal modules - Optional low phase noise configuration (Option UNY) The Keysight N5227B is a PNA network analyzer offered in 2-port and 4-port configurations. Standard models cover 10 MHz to 67 GHz, while Low Frequency Extension (LFE) options extend the measurement range down to 900 Hz (specified), giving a continuous 900 Hz to 67 GHz span on a single instrument. Typical performance information is also provided between 67 GHz and 70 GHz. The analyzer uses 1.85 mm (male), 50 Ω test port connectors. A network analyzer of this type measures the reflection and transmission characteristics of a device under test — the S-parameters that describe how a component or network responds to applied RF and microwave signals. The N5227B's specifications are organized around reflection measurements (Sii) and transmission measurements (Sij), corrected system performance after full 2-port calibration, and group delay derived from measured phase change across a selectable aperture. ValueTronics stocks and holds its own inventory in a 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every pre-owned instrument is inspected and functionally verified in-house before it ships, while new units ship factory-sealed exactly as received from the manufacturer. Holding our own stock lets us match the right configuration to the application and stand behind what we sell. ## Brand Heritage Keysight Technologies traces its measurement heritage through Hewlett-Packard, whose test and measurement business was spun off as Agilent Technologies in 1999. Agilent's electronic measurement division was then established as Keysight Technologies in 2014. ## Product Core & Specifications Specification Value Frequency Information (Table 6, All Options) N5227B Frequency Range 10 MHz to 67 GHz (specification); 67 GHz to 70 GHz (typical) N5227B Frequency Range (LFE Options) 900 Hz to 67 GHz (specification); 500 Hz to 900 Hz (typical) Frequency Resolution 1 Hz Frequency Accuracy ±0.7 ppm Initial Frequency Accuracy ±0.2 ppm (specification); ±0.1 ppm (typical) Frequency Stability ±0.05 ppm, -10° to 70° C; ±0.5 ppm (first year) (typical) Test Port Output — Power (Tables 11, 12, 23) Nominal (Preset) Power, Option 200/201/205/400/401/405 0 dBm Nominal (Preset) Power, Option 219/220/419/420 \-5 dBm Power Resolution 0.01 dB Maximum Settable Power 30 dBm (typical) Minimum Settable Power, Option 200/201/205/400/401/405 \-30 dBm (typical) Minimum Settable Power, Option 219/220/419/420 \-80 dBm (typical) Power Level Accuracy at Nominal Power (1 GHz to 3.2 GHz) ±1.0 dB (specification); ±0.2 dB (typical) Damage Input Level, Option 200/201/219/400/401/419 27 dBm, 40 V Damage Input Level, All LFE Options 20 dBm, 50 V Test Port Input — Noise Floor (Table 16a, @ 10 Hz IFBW, All Options) 1 GHz to 10 GHz \-114 dBm (specification); -119 dBm (typical) 13.5 GHz to 24 GHz \-116 dBm (specification); -121 dBm (typical) 24 GHz to 26.5 GHz \-117 dBm (specification); -121 dBm (typical) 60 GHz to 67 GHz \-101 dBm (specification); -108 dBm (typical) Corrected System Performance — N5227B with 85058B Calibration Kit (Table 4a, Specification dB) Directivity 35 dB (10 MHz to 2 GHz), 38 dB (2 GHz to 20 GHz), 37 dB (20 GHz to 50 GHz), 34 dB (50 GHz to 67 GHz) Source Match 34 dB (10 MHz to 2 GHz), 40 dB (2 GHz to 20 GHz), 41 dB (20 GHz to 35 GHz), 42 dB (35 GHz to 50 GHz), 40 dB (50 GHz to 67 GHz) Load Match 34 dB (10 MHz to 50 MHz), 35 dB (50 MHz to 2 GHz), 37 dB (2 GHz to 20 GHz), 36 dB (20 GHz to 50 GHz), 33 dB (50 GHz to 67 GHz) Reflection Tracking, Magnitude 0.019 dB (10 MHz to 2 GHz), 0.033 dB (2 GHz to 35 GHz), 0.020 dB (35 GHz to 50 GHz), 0.030 dB (50 GHz to 67 GHz) Reflection Tracking, Phase 0.125° (10 MHz to 2 GHz), 0.218° (2 GHz to 35 GHz), 0.132° (35 GHz to 50 GHz), 0.198° (50 GHz to 67 GHz) Transmission Tracking, Magnitude 0.159 dB (10 MHz to 50 MHz), 0.128 dB (50 MHz to 2 GHz), 0.099 dB (2 GHz to 10 GHz), 0.094 dB (10 GHz to 20 GHz), 0.100 dB (20 GHz to 35 GHz), 0.093 dB (35 GHz to 50 GHz), 0.121 dB (50 GHz to 60 GHz), 0.137 dB (60 GHz to 67 GHz) Transmission Tracking, Phase 1.047° (10 MHz to 50 MHz), 0.845° (50 MHz to 2 GHz), 0.655° (2 GHz to 10 GHz), 0.619° (10 GHz to 20 GHz), 0.663° (20 GHz to 35 GHz), 0.616° (35 GHz to 50 GHz), 0.801° (50 GHz to 60 GHz), 0.903° (60 GHz to 67 GHz) Stability, All Options - Typical (Table 22a) 50 MHz to 3.2 GHz 0.01 dB/°C; 0.100 °/°C 3.2 GHz to 20 GHz 0.01 dB/°C; 0.200 °/°C 50 GHz to 67 GHz 0.03 dB/°C; 0.600 °/°C Miscellaneous Information (Table 26) System IF Bandwidth Range 1 Hz to 15 MHz, nominal LXI Class C Front Panel Information (Table 27, All Options) RF Connectors, Type 1.85 mm (male), 50 ohm, (nominal) RF Connectors, Center Pin Recession 0.002 in.

The performance is degraded at particular frequencies in this range due to the modes of the 1.85 mm connectors used in the analyzer, test port cables and adapters. > **Important:** With an LFE option, the LFE measurement range overlaps with the standard measurement range from 10 MHz to 100 MHz. With LFE Enabled, measurements from 500 Hz to 100 MHz use LFE hardware. To measure below 10 MHz, LFE must be enabled. > **Important:** All measurements above 100 MHz use standard hardware, regardless of the LFE Enabled/Disabled setting. > Recommended pairing: corrected system performance is specified with the 85058B mechanical calibration kit and the N4694A and N4694D 2-port ECal modules. ## About this Pre-Owned unit This pre-owned unit is inspected and functionally verified in-house before it ships and is backed by our pre-owned warranty.
