Keysight P5003A Vector Network Analyzer Repair
The Keysight P5003A is a Streamline USB vector network analyzer (to ~9 GHz) — a 2-port VNA 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, the synthesizer, and the USB/control interface.
June Company repairs and calibrates the Keysight P5003A for RF engineering and component-test teams.
Common Keysight P5003A 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.
- Won’t enumerate / USB-control faults — the USB interface the PC software needs, restored.

FAQs
My P5003A cal won’t hold or it won’t connect — fixable? Yes. Synthesizer, receiver, and USB-interface 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.
