In order to have a frequency stabilization system (FSS) working with a new frequency modulation (FM)

I collect some notes of things that need to be done;

In vacuum cavities

1. Choose the FM for both South and North cavities;
   1. Currently we are using ~14MHz;
   2. PMC are not into the path;
2. Buy the oscillators;
3. Modify the photodetectors to the right frequencies or build new ones;
4. Buy one BB EOM
   1. Currently we have a resonant ~14MHz and one BB with an external resonant circuit;
5. Build two resonant circuits for the BB EOMs: one applied to what we already have just replacing the external circuit and one to new BB EOM that we will buy;
6. We need to buy (perhaps) a HV driver;
7. Later we may need to modify the FSS servo board;
8. (...please add if something is missing...)

PMCs

In parallel and/or later in order to implement both the PMCs in the North and South path we need:

1. Buy one BB EOM;
   1. We currently have a resonant 21.5MHz;
2. Build a resonant circuit at 21.5MHz;
3. Build a resonant photodetector at 21.5MHz;
   1. We currently have one at that frequency;
4. Build two servo boards for both PMCs;
   1. We may have one available;
