Description

Keysight N9021B Signal Analyzer Repair

The Keysight N9021B is an MXA signal analyzer (to ~50 GHz) — a high-performance bench analyzer for spectrum and signal/modulation analysis on wireless, radar, and microwave signals. As a precision RF receiver, its faults concentrate in the RF front-end (mixer, attenuator), the synthesizer/LO, the IF/ADC path, and the display.

June Company repairs and calibrates the Keysight N9021B for wireless, radar, and microwave test teams.

Common Keysight N9021B problems we fix

Modulation-analysis faults — the modulation/vector analysis returning wrong results from a front-end or IF fault, repaired.
Input-mixer / front-end degradation — mixer damage (often from overload) degrading sensitivity, repaired.
Amplitude or frequency accuracy off — front-end or synthesizer drift, recalibrated against standards.
Attenuator faults — the input step attenuator, repaired.
Display or interface faults.

FAQs

My N9021B modulation results or sensitivity are off — fixable? Yes. Front-end and IF faults are repairable and recalibrated, then verified so amplitude, frequency, and modulation 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.
