Keysight P5001A Vector Network Analyzer Repair
The Keysight P5001A is a Streamline USB vector network analyzer — a 2-port VNA (to ~9 GHz) that connects to a PC over USB to measure S-parameters on components, cables, and devices without a built-in display. As a precision RF instrument, its faults concentrate in the source and receiver chains, the test ports, and the USB/control interface.
June Company repairs and calibrates the Keysight P5001A for RF engineering and component-test teams.
Common Keysight P5001A 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.
- Won’t enumerate / USB-control faults — the USB interface the PC software needs, restored.
- Source or receiver faults — no stimulus or low sensitivity, repaired.
- Power or internal faults.
FAQs
My P5001A won’t connect or cal won’t hold — fixable? Yes. USB-interface and source/receiver faults are repairable, then verified so it links to your software and measures stable S-parameters, 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.
