Description

Keysight N5234B Microwave Network Analyzer Repair

The Keysight N5234B is a PNA-L microwave network analyzer covering up to 43.5 GHz — a multi-port VNA for measuring S-parameters on microwave components, cables, and devices. As a precision microwave instrument, its faults concentrate in the source and receiver chains, the test-set/port hardware, and calibration stability.

June Company repairs and calibrates the Keysight N5234B for RF/microwave and antenna/satellite test teams.

Common Keysight N5234B problems we fix

Port or test-set damage — a damaged measurement port from overpower or connector wear degrading S-parameter accuracy, repaired.
Calibration won’t hold / fails — source, receiver, or directivity faults making cal unstable, tracked down and repaired.
Source or LO faults — no stimulus or unstable output, restored.
Receiver / mixer faults — low sensitivity or bad traces, repaired.
Display or interface faults.

FAQs

My N5234B cal won’t hold — fixable? Yes. Unstable cal usually points to the source, receiver, or a worn port; we repair the cause and verify stable S-parameter measurement, 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.
