Digitalization of Squeezing Measurements

Working on getting squeezing measurements and calculation from digital channel (Homodyne DC_DIFF) with scripts instead of SR785 screenshots all the time. (This answers the question from Jeff after today's noon meeting.)

This will also help us with lower frequency squeezing information that Georgia suggested.

Some first version matlab code can be find here

The plot shown is an example with 3.1dB SQZ and 6dB aSQZ.


Also going to look into the predicted optical loss and phase noise from the squeezing information (NLG, Green power, squeezing level) and measurements we already have.
