The Keysight N9917B FieldFox Handheld Microwave Analyzer delivers integrated RF and microwave measurement capability to 18 GHz in a single portable platform. It combines cable and antenna analysis, vector network analysis, spectrum analysis, and power measurement functions—eliminating the need for multiple instruments during field deployment, maintenance, and troubleshooting. The 50 Ω system impedance (75 Ω capable with appropriate adapter and calibration kit) and dual built-in ports support demanding measurement scenarios across cellular, satellite, radar, and electronic warfare applications.
