Description

Keysight N9938A FieldFox Spectrum Analyzer Repair

The Keysight N9938A is a FieldFox handheld spectrum analyzer covering up to 26.5 GHz — a ruggedized field instrument for spectrum monitoring, interference hunting, and microwave/transmitter testing. As a precision handheld RF instrument, its faults concentrate in the RF front-end (mixer, attenuator, YIG/LO), the synthesizer, the test port, and the display.

June Company repairs and calibrates the Keysight N9938A for RF, radar, and wireless field engineers.

Common Keysight N9938A problems we fix

Input-attenuator faults — the input step attenuator not switching correctly, repaired and recalibrated.
Tracking-generator faults — the optional tracking generator not producing correct output, repaired.
Mixer / front-end damage — sensitivity loss from overload, repaired.
Amplitude or frequency accuracy off — front-end or synthesizer drift, recalibrated against standards.
Touchscreen, display, or battery faults.

FAQs

My N9938A attenuator or tracking generator is off — fixable? Yes. Attenuator, tracking-generator, 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.
