Description

Rohde & Schwarz ZNB40 Vector Network Analyzer Repair

The Rohde & Schwarz ZNB40 is a benchtop vector network analyzer covering up to 40 GHz — a high-performance 2- or 4-port VNA for S-parameter measurement on microwave components, cables, and devices. As a precision microwave instrument, its faults concentrate in the source and receiver chains, the test-set/port hardware, and the synthesizer/reference.

June Company repairs and calibrates the R&S ZNB40 for RF/microwave engineering and component-test teams.

Common R&S ZNB40 problems we fix

  • Port-extension / time-domain faults — the port-extension or time-domain functions returning wrong results from a measurement fault, repaired and recalibrated.
  • Source and receiver restoration — no stimulus or low receiver sensitivity skewing S-parameters, repaired.
  • Test-port damage — a worn or damaged port from overpower or connector wear, repaired.
  • Calibration won’t hold — directivity/match faults, tracked down.
  • Display or interface faults.

FAQs

My ZNB40 cal won’t hold — fixable? Yes. Receiver, source, and port faults are repairable and recalibrated, then verified so S-parameter measurement is stable and accurate, 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.
