Subject: etmx slow daq chassis 

Some suggestions of checks to run, based on the rightmost colum in the wiring diagram here - I guess some of these have been done already, just noting them here so that results can be posted.

  1. Oplev quadrant slow readouts should match their fast DAQ counterparts.
  2. Confirm that EX Transmon QPD whitening/gain switching are working as expected, and that quadrant spectra have the correct shape.
  3. Watchdog tripping under different conditions.
  4. Coil driver slow readbacks make sense - we should also confirm which of the slow readbacks we are monitoring (there are multiple on the SOS coil driver board) and update the MEDM screen accordingly.
  5. Confirm that shadow sensor PD whitening is working by looking at spectra.
  6. Confirm de-whitening switching capability - both to engage and disengage - maybe the procedure here can be repeated.
  7. Monitor DC alignment of ETMX - we've seen the optic wander around (as judged by the Oplev QPD spot position) while sitting in the control room, would be useful to rule out that this is because of the DC bias voltage stability (it probably isn't).
  8. Confirm that burt snapshot recording is working as expected - this is not just for c1auxex, but for all channels, since, as Johannes pointed out, the 2018 directory was totally missing and hence no snapshots were being made.
  9. Confirm that systemd restarts IOC processes when the machine currently called c1auxex2 gets restarted for whatever reason.
