Description

Rohde & Schwarz ZND Network Analyzer Repair

The Rohde & Schwarz ZND is an economy vector network analyzer (to ~4.5 GHz, extendable to 8.5 GHz) — a 2-port VNA for measuring S-parameters on components, cables, and devices, with a built-in display. As a precision RF instrument, its faults concentrate in the source and receiver chains, the test ports, and calibration stability.

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

Common R&S ZND problems we fix

Receiver calibration drift — the receiver drifting so S-parameter accuracy suffers, recalibrated against standards.
Test-port damage — worn or damaged ports degrading accuracy, repaired.
Source faults — no or unstable stimulus, restored.
Calibration won’t hold — directivity/match faults, tracked down.
Display or interface faults.

FAQs

My ZND cal drifts or won’t hold — fixable? Yes. Receiver and source 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.
