PDH sensing noise:

New lower sensing noise with addition of transformers between LO and RF in both paths.
Cavity unlocked (detuned with temp) noise shows the scatter bump - unsure if this is interesting or should be totally obvious
LBservo noise:

The LB input noise gets to a minimum of 40 nV/rtHz if we turn the gain 100% up at high freq. This is 4x over what they claim
(shown it is 50 nV/rtHz)
Data is all on svn and will be put into noisebudget update |
