Keysight N9912A FieldFox Microwave Analyzer Repair
The Keysight N9912A is a FieldFox handheld RF analyzer (to ~6 GHz) — a ruggedized field instrument combining cable-and-antenna analysis, vector network analysis, and (with options) spectrum analysis for RF field work. As a precision handheld RF instrument, its faults concentrate in the source and receiver chains, the test port, and the display.
June Company repairs and calibrates the Keysight N9912A for RF and wireless field engineers.
Common Keysight N9912A problems we fix

FAQs
My N9912A readings are off — fixable? Yes. Source/receiver and port faults are repairable and recalibrated, then verified so cable-antenna and VNA functions measure accurately, with a NIST-traceable certificate.
Are the ports serviceable? Yes — port reconditioning is routine.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
