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.

If your packaging is damaged or inadequate for the return, we will substitute suitable packaging and may charge the cost of materials.

Insurance. Equipment is not insured by June Company while in transit. We strongly recommend insuring your shipment for its full replacement value.

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.

Return label. A prepaid and preprinted return shipping label should be included with your shipment. If one is not included, we will provide one.
