Portable Keysight N9925A FieldFox Handheld 9 GHz Full Two-Port Vector Network Analyzer
The Keysight N9925A FieldFox is a rugged, portable microwave vector network analyzer with a frequency range of 30 kHz to 9 GHz. This lightweight, durable instrument combines multiple measurement capabilities including full two-port network analysis, cable and antenna analysis, distance-to-fault testing, power measurement, and vector voltmeter functionality.
- VNA frequency range: 30 kHz to 9 GHz
- Transmission/reflection measurements (S21 and S11, magnitude and phase)
- CalReady, OSL, response, and enhanced response calibration
- Lightweight design at only 6.6 lb (3.0 kg)
- Customizable with optional software applications
- Expandable capabilities with optional two-port VNA, TDR, vector voltmeter, and cable/antenna analyzer
- USB power sensor support for average and pulse power measurements
- Simultaneous four S-parameter measurement with up to 95 dB dynamic range (with option)
Options can be added to your order from the accessories section:
- VNA time domain
- VNA full 2-port S-parameters
- TDR cable measurement
- Cable and antenna analysis
- Vector voltmeter
- USB power sensor support
FieldFox can be configured with full 2-port capability for measurements of all four S-parameters and full 2-port calibration. This allows measurement of forward and reverse characteristics without disconnecting and reconnecting components, providing the best possible measurement accuracy.
