Today we set up a method of quickly taking transfer functions of the IMC using an SR785 in the LVEA.
Richard plugged in a GPIB to the CDS network and activated the port at IP 10.22.10.31, GPIB address 10.  
I was then able to quickly take an IMC OLG transfer function using EricQ's netgpibdata scripts, in particularly the SRmeasure script which tells the SR785 what to measure and returns the data.  
This is very useful because the IMC has been unlocking over the past few days, but if we wanted to check the OLG for instability we had to go into the LVEA.

At 11 Watts input power, the IMC OLG is 30 kHz with 58 degrees phase margin.
