Keysight M9375A Vector Network Analyzer Repair
The Keysight M9375A is a PXIe vector network analyzer module (to ~26.5 GHz) — a 2-port modular VNA that installs in a PXIe chassis to measure S-parameters in integrated and automated test systems. As a precision RF instrument, its faults concentrate in the source and receiver chains, the test ports, the synthesizer, and the PXIe/control interface.
June Company repairs and calibrates the Keysight M9375A for RF manufacturing and integrated-test teams.
Common Keysight M9375A problems we fix
- Test-port connector wear / damage — worn or damaged ports degrading accuracy, reconditioned or repaired.
- Source-power-level faults — the source not delivering correct stimulus power, recalibrated against standards.
- Receiver faults — low sensitivity skewing S-parameters, repaired.
- PXIe / control-interface faults — the module not initializing in the chassis, restored.
- Calibration won’t hold — directivity/match faults, tracked down.
FAQs
My M9375A source level or ports are off — fixable? Yes. Source, receiver, and port faults are repairable and recalibrated, then verified so S-parameter measurement is stable and accurate, with a NIST-traceable certificate.
Are the ports serviceable? Yes — port repair is routine.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
