[dsg-hallb_svt] Debugging SVT DAQ

Hi Yuri,

I'm still on vacation but trying to catch up on emails, I'll try and troubleshoot R1 M2 some more on Monday night. There isn't really any pins specifically for registers 17 & 18 so it's a bit concerning that only those are failing. It's just shift in, shift control, shift out and the bco clock lines to read the registers, but those are shared among all the chips on a module. So it being a bad cable or connector if 3/4 of the chips pass 100% and 1/4 chips pass on all but 2 registers would be strange indeed.

For the MVT cables, is help still needed there? If so is there some sort of procedure that someone could follow or is it just a visual inspection of the cables? For the labeling do we need to provide the supplies or are they already on-site? Is there a naming scheme to follow for them?

Dear Marco,

We need Brian's expertise in debugging the SVT DAQ issue we need to resolve. We did not get feedback about his availability for this task. SVT integration will be on hold for now, we continue with BMT integration.
