There are fewer lies on this screen now. For reference, the details of the electronics modifications made are in this elog.

  1. Error and control signals are now in units of nm, the appropriate filter switches have been SDF'ed.
  2. I think it's useful to see the control voltage to the PZT in volts as well, so I've made two readbacks available at the control point, one in V and one in nm.
  3. Indicated that the on-board LO mon readback, which reads "nan", is no longer meaningful, as the mixer is off the demod board.
  4. Indicated that the PMC Trans readback of "0" is because of a dead ADC.

I think many of the readbacks on the PMC MEDM screen are now bogus and misleading since the PMC RF upgrade that Gautam did awhile ago. We ought to fix the screen and clearly label which readbacks and actuators are no longer valid.
