The Keysight N9923A is a FieldFox handheld RF vector network analyzer. The standard frequency range of this device is 2 MHz – 4 GHz, however, this is upgradable to 6 GHz via option N9923A-106.
- Standard measurements: S11, S21 magnitude and phase
- Measurements with option 122: S22, S12 magnitude and phase
- Formats: Log magnitude, linear magnitude, VSWR, phase, Smith chart, polar, group delay, unwrapped phase, real, imaginary
The first step in ensuring that wireless communication systems are running at their optimum level is to verify that RF components in the system, such as cables, antennas, and filters are properly tested and kept in good condition. The majority of these tests are conducted in the field or in a warehouse, where bench top instruments are not readily available, testing space is limited, or where a power source is simply not available. The Keysight Technologies, Inc. handheld FieldFox RF Vector Network Analyzer (VNA) is designed to make network analysis measurements in the field easier, convenient, and the most reliable.
Unmatched reliability for day-to-day tests
Whether you are testing a flight line for the air force, an RF system on a war ship, a wireless communication cable and antenna system, tuning RF components, or making other general purpose network analyzer measurements — the FieldFox RF VNA provides unmatched measurement reliability, stability, and efficiency for your every day test needs. The FieldFox RF VNA also builds on Keysight’s 40-year legacy of network analysis leadership in calibration, accuracy, and innovation.
Vector Network Analysis
The base FieldFox RF VNA provides transmission/reflection (T/R) measurements, or S11 and S21, with magnitude and phase.
Adding Option 122 (full 2-port S-parameters) brings new levels of accuracy and convenience for testing RF components. A full 2-port network analyzer lets you measure the forward and reverse characteristics of your components without having to disconnect, turn around, and reconnect them to the analyzer.
It also provides full 2-port calibration to give you the best measurement accuracy possible. Depending upon your application, you can choose the optimum performance level of an S-parameter analyzer (Option 122) or transmission reflection analyzer (base model).
You also can simultaneously measure and view all four S-parameters, with a single connection.
FieldFox VNA contains four independent, sensitive receivers. The receivers provide more than 100 dB of dynamic range for vector measurements of high rejection, narrowband devices such RF filters. The receivers also make possible full 2-port error correction with the Unknown Thru method, allowing you to measure non-insertable devices.
