Description
Vector Network Analyzer Repair
June Company repairs and calibrates vector network analyzers (VNAs) from all major manufacturers — Keysight, Anritsu, Rohde & Schwarz, Copper Mountain, and more. A VNA measures S-parameters (magnitude and phase) to characterize RF and microwave components, antennas, filters, and cables, so a fault anywhere in its source, receiver, or test-set path undermines every measurement.
If you tell us the make and model, we’ll confirm the specific repair — the workflow and warranty are the same across brands.
Common vector network analyzer 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 that make cal unstable, tracked down and repaired.
- Source or LO faults — no output or unstable stimulus, restored.
- Receiver / mixer faults — low sensitivity or bad traces, repaired.
- Display, connector, or interface faults.
FAQs
My VNA calibration won’t hold — fixable? Yes. Unstable cal usually points to the source, receiver, or a worn port; we repair the cause and verify stable S-parameter measurement, with a NIST-traceable certificate.
Which brands do you handle? All major VNA makers — tell us the model and we’ll confirm.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
