The Keysight N9960A is a FieldFox handheld spectrum analyzer covering up to 32 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 N9960A for RF, radar, and wireless field engineers.
Common Keysight N9960A problems we fix

FAQs
My N9960A amplitude or RBW is 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.
