Keysight N9344C Spectrum Analyzer Repair
The Keysight N9344C is a handheld spectrum analyzer (to ~20 GHz) — a ruggedized field analyzer 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), the synthesizer/LO, the IF path, and the display.
June Company repairs and calibrates the Keysight N9344C for RF, microwave, and wireless field engineers.
Common Keysight N9344C problems we fix
- Dynamic-range / noise-floor degradation — front-end or IF faults raising the noise floor, repaired and recalibrated.
- Mixer or attenuator faults — front-end damage from overload, repaired.
- Amplitude or frequency accuracy off — front-end or synthesizer drift, recalibrated against standards.
- Display or keypad failure — repaired.
- Battery or power faults.
FAQs
My N9344C noise floor went up — fixable? Yes. Front-end and IF faults are repairable and recalibrated, then verified so dynamic range, 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.
