CARM OLG Measurement during 2W using SR785
M. Todd, S. Dwyer
Following the same routine layed out in alog 64204, we had the SR785 already plugged in for a CARM OLG measurement using the gpib from the control room.
I adjusted the carm olg template a tiny bit as it didn't have the right gpib number.
Then I ran
cd /ligo/gitcommon/psl_measurements/code
conda activate labutils
python SRMeasure.py ../templates/carm_olg_template.yml
conda activate labutils
python SRMeasure.py ../templates/carm_olg_template.yml
I measured a 11kHz UGF with a 41 degree phase margin; while this is quite different from previous measurements (2022-07-29) which had something around 27 kHz, I think this is because of the different power states.
