Keysight N9950A FieldFox Microwave Analyzer Repair
The Keysight N9950A is a FieldFox handheld microwave analyzer covering up to 32 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 N9950A for microwave, radar, and wireless field engineers.
Common Keysight N9950A problems we fix

- Port-connector damage — worn or damaged test port from field use, repaired.
- Touchscreen or display failure — repaired.
- Battery or power faults.
FAQs
My N9950A frequency or readings drifted — fixable? Yes. Synthesizer, source/receiver, 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.
