Description

Keysight N9933B FieldFox Spectrum Analyzer Repair

The Keysight N9933B is a FieldFox handheld spectrum analyzer covering up to 9 GHz — a ruggedized field instrument for spectrum monitoring, interference hunting, and transmitter/RF testing. As a precision handheld RF instrument, its faults concentrate in the RF front-end (mixer, YIG/LO), the synthesizer, the test port, and the display.

June Company repairs and calibrates the Keysight N9933B for RF, radar, and wireless field engineers.

Common Keysight N9933B problems we fix

Mixer replacement — front-end mixer damage (often from overload) degrading sensitivity and accuracy, replaced.
YIG-oscillator / LO faults — the tuned oscillator drifting or failing, repaired and recalibrated.
Amplitude or frequency accuracy off — front-end or synthesizer drift, recalibrated against standards.
Touchscreen or display failure — repaired.
Battery or power faults.

FAQs

My N9933B sensitivity or accuracy dropped — fixable? Yes. Mixer and LO faults are repairable and recalibrated, then verified so amplitude and frequency accuracy are restored across the range, 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.
