A special flexible differential cable was designed to keep the delay change to 5pS while torqued/twisted 180 degree This cable drives the SRD differentially. The two extra wire provide the sampler bias and send back the average value of the sampled signal. | A special flexible differential cable was designed to keep the delay change to 5pS while torqued/twisted 180 degree This cable drives the SRD differentially.

This device, the SD-20, and for that matter the [[S-6]] of the 7K generation all suffered from customer inattention to ESD issues - there were a lot of repairs needed. As a result, our 8000-series never included a loop through feature, although we do support high BW [[TekConnect_connector|TekConnect]] probes through the [[80A03]]. And furthermore, all of our samplers now run open loop, with on-the-fly point correction for the front end nonlinearity, so there is no loop gain correction needed. | This device, the SD-20, and for that matter the [[S-6]] of the 7K generation all suffered from customer inattention to ESD issues - there were a lot of repairs needed.
