Description

Keysight N9961A FieldFox Spectrum Analyzer Repair

The Keysight N9961A is a FieldFox handheld spectrum analyzer covering up to 44 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, the synthesizer/LO, the test port, and the display.

June Company repairs and calibrates the Keysight N9961A for RF, radar, and wireless field engineers.

Common Keysight N9961A problems we fix

Resolution-bandwidth / amplitude accuracy off — front-end or IF-path drift, recalibrated against standards so RBW and amplitude are accurate.
RF input / front-end damage — overload or connector damage degrading sensitivity, repaired.
High noise floor / no signal — front-end or LO faults, restored.
Touchscreen or display failure — repaired.
Battery or power faults.

FAQs

My N9961A amplitude readings are off — fixable? Yes. Front-end and IF-path 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.
