We instead productized the [[SD-20]] module in the Lab Scopes HFCD product area, which essentially was our 20 GHz sampler from the [[SD-23]] / [[SD-24]] designs but with the 50 Ohm coax fed back out to the front panel instead of having the built in internal 50 Ohm termination on the channel. And it was fully calibrated, since it didn’t have the modularity of this other proposal. | We instead productized the [[SD-20]] module in the Lab Scopes HFCD product area, which essentially was our 20 GHz sampler from the [[SD-23]] / [[SD-24]] designs but with the 50 Ohm coax fed back out to the front panel instead of having the built in internal 50 Ohm termination on the channel.

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 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.
