Description

Keysight N5231B Microwave Network Analyzer Repair

The Keysight N5231B is a PNA-L microwave network analyzer (to ~13.5 GHz) — a 2- or 4-port VNA for S-parameter measurement on microwave components, cables, and devices in design and production. As a precision microwave instrument, its faults concentrate in the source and receiver chains, the test-set/port hardware, and the synthesizer/reference.

June Company repairs and calibrates the Keysight N5231B for RF/microwave engineering and component-test teams.

Common Keysight N5231B problems we fix

Source-leveling errors — the source not delivering correct stimulus power, recalibrated against standards.
Receiver sensitivity loss — receiver/mixer degradation skewing S-parameters, repaired.
Test-port / test-set damage — a damaged port from overpower or connector wear, repaired.
Calibration won’t hold — directivity/match faults, tracked down.
Display or interface faults.

FAQs

My N5231B source level or sensitivity is off — fixable? Yes. Source-leveling and receiver faults are repairable and recalibrated, then verified so S-parameter measurement is stable and accurate, with a NIST-traceable certificate.

Is the test set serviceable? Yes — port and test-set repair is routine on PNA-L analyzers.

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