PSL RF status

Michael, Rick, Kiwamu

All servos are now running on the aLIGO RF sources. The final step on Friday was to lock the FSS and tune up the servo. We used one full box for the delay line to set the phase, with 24 ns delay in the first half and 7 ns delay in the second. The common gain was set to 18 dB, up from 17 dB before. This gave us a UGF at 400 kHz with 58 degrees of phase margin. We are still running on the old RFPD and will have to install the new one at some point.
