We measured the sqz, asqz, and mean sqz with current NLG as shown in the attached figure. The current OPO green trans is 85 and it corresponds to NLG of 12.6 and generated sqz of 15.5dB according to the calibration done on 2/3/23. 

To measure the mean sqz, we paused the SQZ MANAGER guardian and turned off SQZ ASC and took LO guardian down.

At 1kHz, squeezing is 3.7dB, mean squeezing is 10.4dB, and anti squeezing is 13.3dB.

We will measure the NLG with seed and try high NLG tomorrow.
