DCS tested the WISE isolators most of the day.

Discussed RR with Brad and Paul. They suggested gain tuning a little differently to try and get it more accurate. They suggested turning the variable resister in 1/8th of a turn increments and taking an FFT of the differenced velocity when the input to the system was a 40Hz sine wave. Which ever position had the lowest value at 40Hz would be the best gain matched position. I did this and the resulting room temp rejection ratio when gain tuned like this was a bit better than before. Now Brad and Paul want me to retake the 100F and 32F RR measurements.
