Common mode board A at H2 EY (S/N S1102638) (Jax S., Daniel S.) We changed the common generic filter to a double pole 100kHz/Q=0.85. This is to replace the Pomona box that was used to suppress the PZT resonance around 250kHz-300kHz. R129 -> 2.67K R130 -> 1.30K R131 -> 0 R132 -> 0 C207 -> 1.5n C206 -> 470p This allowed us to push the ugf to just above 30kHz with a phase margin of 45 degrees. We backed off with the gain set to -6dB in the input section which leaves us with a ugf around 28kHz and a phase margin of close to 50 degrees. Common mode board B at H2 EY (S/N S1102637) We also changed the fast monitor into the Beckhoff on the cavity locking servo to be unity gain rather than 10. R271 -> 0 R272 -> NL
