Keysight (Agilent) N9926A FieldFox Handheld Microwave Vector Network Analyzer, 14 GHz

The Keysight N9926A FieldFox is a battery-operated handheld vector network analyzer combining VNA, cable and antenna analyzer, spectrum analyzer, and power meter functionality in a single 3.0 kg ruggedized unit. Operating from 30 kHz to 14 GHz, it delivers simultaneous four-parameter S-parameter measurements with up to 100 dB dynamic range to 9 GHz and 94 dB to 14 GHz. The instrument supports transmission/reflection base measurements and optional full 2-port characterization, with calibration modes including QuickCal, TRL, OSL, and enhanced response calibration. Trace noise of 0.004 dB rms ensures precision in demanding field environments.
