LIGO Document E1800338-v2
- The common mode servo of the interferometer suffers from noise in the DAQ readbacks that are due to large high frequency signals. There is also a lack of boost filters to squash the low frequency noise below 100Hz.
- Add extra gain of 5 to error DAQ readback (R56)
- Add extra 15kHz poles to slow & fast DAQ readbacks (C242 and C293)
