Description
Keysight M9817AS Vector Component Analyzer Repair
The Keysight M9817AS is a PXIe vector network/component analyzer — a modular VNA (a 2-port PXI analyzer) that installs in a PXI chassis to measure S-parameters and component characteristics, including balanced/differential measurements, in integrated 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 M9817AS for RF manufacturing and integrated-test teams.
Common Keysight M9817AS problems we fix
- Balanced / differential measurement faults — a port or path skewing balanced measurements, repaired and recalibrated.
- Source / receiver chain faults — no or weak measurement, restored.
- Test-port damage — worn or damaged ports degrading accuracy, repaired.
- PXIe / control-interface faults — the module not initializing in the chassis, restored.
- Calibration won’t hold — directivity/match faults, tracked down.
FAQs
My M9817AS balanced measurements are off — fixable? Yes. Source, receiver, and port faults are repairable and recalibrated, then verified so S-parameter and balanced measurements are 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.
