This unit
The Keysight N9933B FieldFox is a handheld RF vector network analyzer combining VNA, cable and antenna analyzer, and spectrum analyzer capabilities in a single ruggedized unit. Operating from 9 kHz to 4 GHz, it delivers field-grade measurements without requiring external calibration kits or warm-up periods. The instrument features 100 dB dynamic range for 2-port transmission, real-time spectrum analysis with 120 MHz bandwidth, and built-in CalReady technology for rapid field calibration with temperature drift compensation.
