The Keysight N9916B FieldFox is a handheld microwave combination analyzer delivering RF and microwave measurements up to 14 GHz in a portable 3.4 kg platform. Built for field installation, maintenance, and troubleshooting of RF components—cables, antennas, filters, amplifiers—and signal analysis, the N9916B integrates cable and antenna analysis as standard with optional vector network analysis, spectrum analysis, and real-time spectrum capture.
