Find the perfect TDR for your Application

Carrying out laboratory applications or pre-compliance measurements is just as much a part of our day-to-day business as recurring series measurements in quality assurance testing.

You deal with controlled impedance design and signal-integrity testing?

We offer TDRs for wave impedance profile measurements of PCBs, connectors & cables.

Would you like to measure differential or mixed-mode S-parameters?

Then you are sure to find the right device among our product

Are safe and portable devices important to you?

Our TDRs are all portable, but you don't have to compromise on ESD safety. Battery-powered TDRs allow you to take measurements outdoors and in remote locations.
