The Keysight (Agilent) N9917A FieldFox is a rugged, handheld 18 GHz microwave combination analyzer engineered for demanding field test environments. Its base configuration provides high-accuracy cable and antenna analysis (CAT), with optional capabilities for full two-port vector network analysis (VNA), spectrum analysis (SA), interference analysis, vector voltmeter (VVM), and built-in power meter. Built to MIL-PRF-28800F Class 2 standards, it combines laboratory-grade trace noise and dynamic range with portable, weather-resistant durability.
