Signal Generator Repair

Signal Generator Repair & Calibration

June Company repairs and calibrates signal generators from every major manufacturer, including Keysight, Rohde & Schwarz, Anritsu, and Tektronix. We service RF, microwave, vector, and function/arbitrary generators — restoring output accuracy and bringing each unit back to manufacturer specification with NIST-traceable calibration.

Models We Commonly Repair

Keysight N5181/N5182 MXG, E8257D PSG, and 33500 function generators; Rohde & Schwarz SMB and SMW; Anritsu MG369x; and comparable units from other makers. For waveform generators specifically, see our waveform generator repair page. If your model isn’t listed, we almost certainly still service it — send us the details.

Common Faults We Resolve

Output level or frequency accuracy out of tolerance, RF output and modulation failures, attenuator faults, display and interface problems, communication errors, and power-supply issues. Every repair includes full functional testing and NIST-traceable calibration of output parameters, documented on a calibration certificate.

Why RF Engineers 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, manufacturers, and aerospace/defense teams from our Oregon facility.
