Description

Keysight N8975B Noise Analyzer Repair

The Keysight N8975B is a noise figure analyzer — it measures noise figure and gain of amplifiers, receivers, and components across its range, a key parameter for RF/microwave receiver sensitivity. As a precision measurement receiver, its faults concentrate in the RF front-end, the measurement/IF path, and the noise-source drive and connectors.

June Company repairs and calibrates the Keysight N8975B for RF/microwave, satellite, and radar engineering teams.

Common Keysight N8975B problems we fix

Receiver sensitivity degradation — front-end or measurement-path drift reducing sensitivity and skewing NF results, recalibrated against standards.
Noise-figure measurement out of spec — measurement-path faults, repaired.
RF input / connector faults — overload or worn connectors, serviced.
Noise-source drive faults — the drive to the noise source, repaired.
Display or interface faults.

FAQs

My N8975B sensitivity dropped — fixable? Yes. Front-end and measurement-path faults are repairable and recalibrated, then verified so NF and gain measurements are accurate, with a NIST-traceable certificate.

Is the noise-source drive checked? Yes — the drive and measurement path are verified against our standards.

Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
