Description

Rohde & Schwarz ZNLE4 Vector Network Analyzer Repair

The Rohde & Schwarz ZNLE4 is a cost-efficient benchtop vector network analyzer (to ~4 GHz) — a 2-port VNA for S-parameter measurement on components, cables, and devices, with a built-in touchscreen. As a precision RF instrument, its faults concentrate in the source and receiver chains, the test ports, the synthesizer, and calibration stability.

June Company repairs and calibrates the R&S ZNLE4 for RF engineering and component-test teams.

Common R&S ZNLE4 problems we fix

Source-power-leveling errors — the source not delivering correct stimulus power, repaired and recalibrated against standards.
Receiver faults — low sensitivity or drift skewing S-parameters, repaired.
Test-port damage — worn or damaged ports degrading accuracy, repaired.
Calibration won’t hold — directivity/match faults, tracked down.
Touchscreen or interface faults.

FAQs

My ZNLE4 source leveling or cal is off — fixable? Yes. Source, receiver, 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.
