We offer a standard 90-day warranty on repairs. We warrant the repaired circuitry will be free of defects for a period of 90 days from the day it ships from Phase Matrix. The warranty covers only the repaired parts. If a part other than the repaired part fails, it is not covered under warranty.



It is important to provide a product's identification numbers. All frequency counters, VXI, PXI, and QuickSyn® products have CCNs. CCN stands for configuration control number and basically indicates the revision or version of a product. Some component and assembly products may not have a CCN. The product's label will contain model and serial number as well as CCN. Delays and difficulties in processing an RMA may occur if this information is incomplete or incorrect.


Indicate which options are present in the product you are intending to return. Options numbers and features vary among products. Each product page on this website shows the possible product options under ordering information.


A fee will be applied if you choose to expedite the service of your unit. See price list.
Describe problem only if your unit needs repair. Skip if you're just returning your unit for calibration.
