Repair Services

If your instrument requires repair, we will be happy to accommodate at either our Indianapolis office or an authorized service center near you. If you need a temporary “loaner” instrument, we will work to provide one so your work is uninterrupted during the evaluation and repair process.


To help facilitate diagnosis of a suspected instrument malfunction, please find, download, and “Recall” the state file below that corresponds to your instrument family. With nothing connected to the instrument ports, perform an Auto Scale on all traces, and send us a screenshot for review (System > Print Windows).


For R-series 1-port VNAs, please send two screenshots after a System > Preset: one with nothing connected to the instrument, and one with a 50 Ohm load connected.

Once you have compiled your screenshots, please submit them to support.
