          @MissingClara And identified the failure point, and a strong suspicion of the two contributing causes

                > It took a bit of experimenting with external GPU enclosures and such to figure out how to get the ThunderScope to sit out on my lab bench so I wouldn’t need to crawl under the bench and run cables up from the workstation on the floor up to probes on my DUT, but I figured that out easily enough.

                I'm looking forward to reading the rest, but I'm also very interested to hear more about this if you're able! I opted for the Thunderbolt variant precisely because I didn't want to dig for connections. Might be reconsidering my choice now... 🤔

                  @attie The keyword to search for is "OCuLink" which is basically just PCIe over cables.

                  On the PC side the adapter card is just a passive PCB taking the differential pairs from a PCIe card edge connector and shoving them over a SFF-xxxx (forget the number) cable.

                  On the enclosure side, typically you have a board with a SFF connector and a 12V DC power inlet that converts it back to a PCIe connector you can slide a card into.

                      @attie note that many oculink carriers are just the card edge connector and provide no side support so i 3d printed a card guide to go around the pcb and keep the TS from wobbling side to side
