LIGO Document E1800074-v1
- Fix the common generic filter and add a notch for the SHG/OPO PZT resonances.
- Daniel adds (via email discussions) to propagate this modification to all SQZ CMS chassis.
Notes from email discussion:
Yes, all SQZ chassis are the same and should receive the same mods.
It's true that it isn't required, but we try to keep all SQZ CM boards identical
to simplify spares.
Indeed, this notches can be bypassed remotely for these boards. Daniel
