Description

Rohde & Schwarz ZNB20 Vector Network Analyzer Repair

The Rohde & Schwarz ZNB20 is a benchtop vector network analyzer covering up to 20 GHz — a high-performance 2- or 4-port VNA for S-parameter measurement on microwave components, cables, and devices, with wide dynamic range. 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 ZNB20 for RF/microwave engineering and component-test teams.

Common R&S ZNB20 problems we fix

Test-port connector wear / damage — worn or damaged ports degrading accuracy, reconditioned or repaired.
Source and receiver restoration — no stimulus or low receiver sensitivity skewing S-parameters, repaired.
Source-leveling errors — the source not delivering correct power, recalibrated against standards.
Calibration won’t hold — directivity/match faults, tracked down.
Display or interface faults.

FAQs

My ZNB20 ports are worn or cal won’t hold — fixable? Yes. Port, source, and receiver 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.
