Keysight N9916B FieldFox Microwave Analyzer Repair
The Keysight N9916B is a FieldFox handheld microwave analyzer (to ~14 GHz) — a ruggedized field instrument combining cable-and-antenna analysis, vector network analysis, and spectrum analysis for microwave field work. As a precision handheld microwave instrument, its faults concentrate in the source and receiver chains, the test port, the synthesizer, and the display.
June Company repairs and calibrates the Keysight N9916B for microwave, radar, and wireless field engineers.

FAQs
My N9916B readings drifted — fixable? Yes. Source/receiver, synthesizer, and port faults are repairable and recalibrated, then verified so VNA, cable-antenna, and spectrum functions measure accurately, with a NIST-traceable certificate.
Are the ports serviceable? Yes — port repair is routine.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
