RF and Microwave Test Equipment Repair

Techmaster repairs RF and microwave test equipment: spectrum analyzers, vector network analyzers, signal generators, power meters and sensors, and cable and antenna analyzers. After repair, each instrument is calibrated before it is returned; RF and microwave calibration to 50 GHz is on our ANAB ISO/IEC 17025 scope at the Vista, Santa Clara and Orlando labs.

We repair instruments from many manufacturers, including older and discontinued models where parts are available. Techmaster is an independent laboratory, not a manufacturer-authorized service center.

How does a repair work?

Send the make, model and serial number with a description of the fault and any error codes. We diagnose the fault and send a quote with the expected timeline and warranty terms for your approval. After repair, the instrument is calibrated and returned with its certificate.

What calibration comes after the repair?

RF and microwave calibration is on Techmaster’s ANAB ISO/IEC 17025 scope at Vista, Santa Clara and Orlando, including power sensor cal factors and SSB phase noise to 50 GHz and noise figure to 26.5 GHz. It is not performed at San Antonio. Exact ranges and uncertainties are on our published accreditation scope.

Need to keep testing while your instrument is away? You can rent rf and microwave test equipment for the repair period.

Frequently asked questions

Can you repair a spectrum analyzer or network analyzer?
Yes. Send the make, model, serial number and a description of the fault or error code, and we reply with a quote, the expected timeline and the warranty terms.
Is an RF instrument calibrated after repair?
Yes. It is calibrated before it is returned. RF and microwave calibration to 50 GHz is on our ANAB ISO/IEC 17025 scope at Vista, Santa Clara and Orlando, so parameters within that scope get an accredited certificate.
Is Techmaster an authorized service center?
No. Techmaster is an independent repair and calibration laboratory, not a manufacturer-authorized service center. It repairs instruments from many manufacturers, including older models, where parts are available.
How long does a repair take, and is there a warranty?
It depends on the fault and on parts availability. We include the expected timeline and the warranty terms with the quote.
