(Lisa, Sheila, Daniel)
We finally added the CM summing node to the common mode path. The signals are hooked-up as follows:
-
ALS-C-REFL_DC_ERR (taken from LS-C-REFL_DC_BIAS)
-
LSC-REFL_RF9_ERR (taken from the REFL_A demodulator Q channel)
-
ALS-C_COMM_A_RF_ERR (taken from the COMM_A PFD output)
-
LSC-REFLAIR_RF9_ERR (taken from the REFLAIR_A demodulator I channel)
Fast readbacks still need to be tested. The medm screen can be accessed from the ALS overview screen.
