Keysight N9962A Microwave Spectrum Analyzer Repair
The Keysight N9962A is a FieldFox handheld microwave analyzer covering up to 50 GHz — a ruggedized field instrument combining spectrum analysis with cable-and-antenna and (option-dependent) network analysis for microwave field work. As a precision handheld RF instrument, its faults concentrate in the RF front-end, the source leveling, the test port, and the display.
June Company repairs and calibrates the Keysight N9962A for microwave, radar, and wireless field engineers.
Common Keysight N9962A problems we fix
- Source leveling errors — the leveling loop drifting and skewing measurements, recalibrated against standards.
- RF front-end / port damage — overload or connector damage degrading sensitivity and accuracy, repaired.
- Amplitude or frequency accuracy off — front-end or synthesizer drift, recalibrated.
- Touchscreen or display failure — repaired.
- Battery or power faults.
FAQs
My FieldFox has leveling errors — fixable? Yes. Source-leveling and front-end faults are repairable and recalibrated, then verified so amplitude and frequency accuracy are restored, with a NIST-traceable certificate.
Is it calibrated across its range? Yes — verified against our reference standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
