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.

Risk of loss. Risk of loss remains with you until your equipment is received at our facility, and transfers back to you when your repaired unit is delivered to the carrier (F.O.B. shipping point). June Company is not responsible for equipment lost, delayed, misdelivered, or damaged in transit, in either direction.
