Description

Keysight M9485A Vector Network Analyzer Repair

The Keysight M9485A is a PXIe multiport vector network analyzer — a modular VNA (to ~9 GHz, many ports) in a PXI chassis for multiport and high-throughput S-parameter measurement in production and R&D. As a precision modular microwave instrument, its faults concentrate in the source and receiver modules, the test ports and switching, and the PXIe/control interface.

June Company repairs and calibrates the Keysight M9485A for multiport RF/microwave and production-test teams.

Common Keysight M9485A problems we fix

Frequency-synthesizer faults — source drift or unlock affecting measurements, repaired and recalibrated.
Port or test-set damage — a damaged measurement port from overpower or connector wear, repaired.
Calibration won’t hold — receiver or directivity faults making cal unstable, tracked down.
PXIe / control-interface faults — the module not initializing in the chassis, restored.
Receiver faults — low sensitivity or bad traces, repaired.

FAQs

My M9485A cal won’t hold or a port is dead — fixable? Yes. Synthesizer, receiver, and port faults are repairable, then verified so multiport 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.
