TF crashed (watchdog trip) last night at 6pm local. Very weird. The attached plots show the details. First plot shows all the excitation channels for a 3 hour period around the watchdog trip, you can clearly see where we were driving at ~3000cts on each exc channel. The second plot shows the V1 excitation channel and the V1 L4C that tripped over a 100 second window. There is a very low drive, but high frequency excitation that does not look like the other parts of the transfer function being run at the time. This excitation is also roughly at the same time as when we were driving on a different (H1) channel. It's unclear whether this is the cause of the trip or not.
Fabrice was able to copy the signal from the excitation channel and send it again with some matlab trickery, but we saw nothing on any of the chambers (HEPI, ISI, SUS) sensors. So we still don't know what caused the trip. Weird.
