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.
We offer TDRs for wave impedance profile measurements of PCBs, connectors & cables.
Then you are sure to find the right device among our product
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.





We offer TDR devices for many different applications. These differ depending on the type of DUT, the type of parameters to be determined and also the required resolution or bandwidth. Please use the table below to get a more detailed overview.
