Description

Keysight N5291A Microwave Network Analyzer Repair

The Keysight N5291A is a broadband PNA network analyzer system — it measures S-parameters from 900 Hz up to 120 GHz in a single sweep using a PNA-X and external frequency-extension modules, for millimeter-wave component and device characterization. As a precision broadband microwave system, its faults concentrate in the source and receiver chains, the frequency-extension modules, the test ports, and calibration stability.

June Company repairs and calibrates the Keysight N5291A for mmWave and microwave engineering teams.

Common Keysight N5291A problems we fix

Port match / test-set faults — port or test-set damage degrading S-parameter accuracy, repaired.
Frequency-extension module faults — a mmWave module not producing or receiving correctly, repaired.
Calibration won’t hold — source, receiver, or directivity faults making cal unstable, tracked down.
Source or receiver chain faults — no stimulus or low sensitivity, restored.
Display or interface faults.

FAQs

My N5291A cal won’t hold or a band is dead — fixable? Yes. Source, receiver, and frequency-extension faults are repairable, then verified so broadband S-parameter measurement is stable and accurate, with a NIST-traceable certificate.

Do you service the mmWave modules? Yes — the frequency-extension modules are tested and repaired with the analyzer.

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