Vector Network Analyzer Repair

Vector Network Analyzer Repair & Calibration

June Company repairs and calibrates vector network analyzers from every major manufacturer, including Keysight/Agilent, Anritsu, Rohde & Schwarz, and Copper Mountain. We service benchtop and handheld VNAs across RF and microwave bands — restoring measurement accuracy and bringing each unit back to manufacturer specification with NIST-traceable calibration.

Models We Commonly Repair

Keysight/Agilent PNA and ENA series (E5071C, N5230A, N5242A, P937xA); Anritsu VectorStar, ShockLine, and 37xxx series (including the 37247B); Rohde & Schwarz ZNB, ZNA, and ZVA; and Copper Mountain VNAs. If your model isn’t listed, we almost certainly still service it — send us the details.

Common Faults We Resolve

S-parameter accuracy out of tolerance, test-port and directional-coupler faults, source and receiver failures, damaged RF connectors, display and touchscreen problems, calibration and self-test errors, communication faults, and power-supply issues. Every repair includes full functional testing and NIST-traceable calibration across the unit’s frequency range, documented on a calibration certificate.

Why RF and Microwave Labs Choose Us

Most repairs finish in 5–10 business days, every job carries a 90-day parts-and-labor warranty, and your evaluation fee is credited toward the repair. We serve RF and microwave labs, antenna and component manufacturers, and aerospace/defense teams from our Oregon facility.
