== Test Status ==

[done] Whitening gain switching test
[done] AA enable/disable switching
[0th order] LO Det Mon channel check
[none] PD I/F board check
[done] QPD I/F board check
[done] CM Board
[none] ALS I/F board


The photos of the latest board can be found as Attachments 3/4

With some input signals, the functionarities of the CM servo switches were tested.

  • Latch logic works. But latch alive signal is missing.
  • IN1 enable/disable, IN2 enable/disable are properly working
  • OUT2 toggle switch for REFL1/REFL2 mon is wokring
  • Boost / Super Boosts are working
  • EXC A enable/disable, EXC B enable/disable switches are working
  • Option 1 and Option 2 now isolate the input when either is enabled (as there is no option board)
  • 79Hz-1.6kHz pole zero pair works fine
  • OUT1 works fine
  • Disable/Enable switch for the fast path works
  • Polarity switch works
  • AO Gain property changes the gain
  • Limitter switch works (Attachments 4/5). The limitter clipps the output at 4~4.5V. The Limitter indicator also works.

After the tests the LSC cables were reconnected (Attachment 6)
