PMC Servo Board
Board is back in. PMC is locked.
Nominal gain is now 15 dB with brick. We need to do more studies:
Find out why there is still 35 MHz signal at the error point. Order some low pass filters to cut off above 35 MHz.
Explore brick + no-brick loop shapes and error spectra.
Measure and set the OLG.
We've left the copper-wrapped lead brick installed to let it slowly conform to the glass better.
