Status: The Keysight ENA, Streamline, and USB vector network analyzers are in current production. We repair and calibrate all of them.
Common Keysight VNA Problems We Fix
- Measurements inaccurate or out of spec / fails calibration — source or receiver module degradation
- Test port connector worn / readings jump when cables are moved
- Internal calibration reference drift
- Won’t connect over USB or PXI — interface communication failure
- Won’t power on / power supply faults on benchtop models
- Won’t boot / firmware or hard-drive corruption
- Fan noisy or failed / thermal shutdowns

Frequently Asked Questions
How much does Keysight VNA repair cost?
Repairs start with a flat evaluation fee that’s credited toward your repair cost. After we diagnose the instrument, you get a firm quote before any work begins — no surprises.
How long does the repair take?
Most Keysight VNA repairs are finished within 5–10 business days of arrival, with expedited turnaround available if you need it back fast.
My measurements are out of spec or won’t calibrate — can you fix it?
Yes. Source and receiver module degradation is one of the most common causes of out-of-spec S-parameter measurements, and it’s repairable at the component level, then verified against our reference standards.
My test port connectors are worn or readings jump when I move the cables — is that repairable?
Yes. Test port connector wear from repeated connections is a routine repair, restored for stable, repeatable measurements.
It won’t connect over USB or PXI — can you fix the interface?
Yes. We repair USB and PXI interface communication faults across the Streamline PXI and USB VNA lines, so the instrument is recognized and controllable again.
It won’t boot or the firmware is corrupted — can you recover it?
Yes. Firmware corruption and hard-drive failures that stop the instrument from booting are repairable, restored to a working, calibrated state.
Do you service all three families — ENA benchtop, Streamline PXI, and USB VNAs?
Yes. We service the full range: the ENA benchtop models, the M9370–M9485A Streamline PXI VNAs, and the P-Series and M9800 USB VNAs up to 110 GHz.
What if my exact model isn’t listed?
We service every Keysight ENA, Streamline, and USB VNA configuration. If your model isn’t in the table, pick the closest match or email us — the process is the same.
Who uses Keysight vector network analyzers?
RF component manufacturers, PCB signal-integrity engineers, materials test labs, production test teams, 5G infrastructure developers, and antenna measurement groups rely on Keysight VNAs for S-parameter characterization. For full manufacturer specifications, see the Keysight E5080B ENA product page.
