I'm running repeated cavity transfer functions to monitor changes in the cavity during the ring heater test. This means that Excitation B on Common Mode Board A will be left on for the duration of the test (~12 h), and that the GPIB unit on the SR785 at EY is in use and should not be contacted.
Suspending this while oplev calibrations and suspension tests are going on. Will comment when I need to turn Excitation B on CMA on again.
