This unit
The Keysight N9938A FieldFox is a portable, battery-operated microwave spectrum analyzer engineered for field testing and troubleshooting across satellite communications, microwave backhaul, military communications, and radar systems. Operating from 5 kHz to 26.5 GHz, it delivers amplitude accuracy of ±0.5 dB without warm-up and spur-free dynamic range exceeding 105 dB. The instrument combines spectrum analysis, optional tracking generator (30 kHz to 26.5 GHz), and built-in power meter (100 kHz to 26.5 GHz) in a rugged, dust-free, fanless chassis that meets MIL-PRF-28800F Class 2 and MIL-STD-810G standards.
Weighing 6.6 lb, the N9938A delivers gap-free real-time analysis with 10 MHz bandwidth and extends measurement capability through I/Q data capture, time gating for pulsed RF, GPS/GNSS geolocation, and optional vector network analyzer functionality.
