Description
Keysight Microwave Network Analyzer Repair
A microwave vector network analyzer (VNA) measures S-parameters — reflection and transmission — on microwave components, cables, and devices, displaying results as magnitude/phase and on a Smith chart for design and production test. June Company repairs and calibrates Keysight microwave network analyzers across the families (PNA, PNA-L, PNA-X, ENA, and FieldFox); tell us your exact model and we’ll confirm the repair.
Whatever the model, a VNA’s faults concentrate in the source and receiver chains, the test-set/port hardware, and the synthesizer/reference — that’s where our repair and calibration focus.
Common Keysight microwave VNA problems we fix
- Calibration won’t hold / S-parameter errors — receiver or directivity faults making cal unstable, tracked down and repaired.
- Source-leveling errors — the source not delivering correct stimulus power, recalibrated against standards.
- Receiver sensitivity loss — receiver/mixer degradation skewing S-parameters and the Smith-chart display, repaired.
- Test-port / connector damage — a damaged port from overpower or wear, repaired.
- Display or interface faults.
FAQs
Which Keysight VNAs do you repair? Most models across the PNA, ENA, and FieldFox families. Tell us the exact model and symptom and we’ll confirm the repair and turnaround.
Is the cal recertified? Yes — S-parameter accuracy is verified against our standards with a NIST-traceable certificate.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
