Keysight N9923A FieldFox Cable and Antenna Analyzer
The Keysight N9923A FieldFox Cable and Antenna Analyzer sets the benchmark as the world’s most accurate handheld vector network analyzer (VNA). Engineered for precision, it delivers an industry-leading measurement stability of 0.01 dB/°C and features the innovative integrated QuickCal calibration capability. This unique feature provides seamless calibration without the need for a bulky calibration kit, delivering reliable and consistent measurement results while out in the field.
The N9923A is specifically designed for field engineers operating in sectors such as aerospace, defense, and network equipment manufacturing. This robust tool is essential for characterizing RF components within mission-critical communication systems. As a comprehensive 2-port network analyzer, it allows users to measure and display all four S-parameters simultaneously, enhancing productivity and analysis capabilities in dynamic environments.
Designed with portability in mind, the Keysight N9923A is lightweight (< 6.2 lbs) and rugged, making it perfect for field use. It enhances the functionality of existing handheld VNAs, offering a more extensive range of network analysis features compared to the flagship N9912A model.
Key Features of the Keysight N9923A include:
- Integrated QuickCal technology for effortless calibration without a cal kit
- Exceptional measurement stability across time and temperature variations
- Compliant with MIL PRF 28800F Class 2 standards, ensuring reliability and durability
- GPS functionality to timestamp measurements with precise location data
- Powerful 4-hour battery life with a field-replaceable design
The FieldFox N9923A delivers T/R measurements (S11 and S21) with both magnitude and phase capabilities. When option 122 is enabled, it facilitates full two-port calibration and simultaneous measurement of all four S-parameters (S21, S11, S12, S22).
Utilizing the sophisticated vector voltmeter (VVM), similar to the HP 8508A, users can measure phase shifts and electrical lengths of various devices. The VVM option also allows for ratio measurements between two channels, either A/B or B/A.
Additional applications of the FieldFox analyzer include distance-to-fault analysis, voltage standing wave ratio (VSWR) testing, absolute power measurements, and the characterization of 75-ohm cable TV devices.
