Include all the measured and modeled transfer functions (with calibrations) taken between this week and last week. This should be pretty much where we operate for the rest of O3. Didn't retake TTFSS transfer function recently but the loop was already well modeled (and had compared it with the real data at one point). The modeled pretty much all checked about except the CLF loop that's missing a factor of ~1.5.
Fast gain is 0dB unless noted otherwise. Guardian should have all the correct filter settings.
---------------------------------------------------------------------------------------------
LO loop (taken with IFO locked)
Calibration: 1.12Vpp at RF3 -14.66dBm.
Common mode board gain (common path): -5dB
Boosts: 0Hz/10Hz, 20Hz/2kHz
Input: In1 for OMC, In2 for HD
CLF loop
Calibration: 2.9Vpp measured at RF6 -2dBm. RF6 was -3dBm during the measurement. Probably close enough.
Common mode board gain common path -9dB, fast path 6dB
Boosts: 0Hz/10Hz, 20Hz/2kHz
Input: Use In2 (Q)
OPO loop
Calibration: 164mVpp measured at 0.4mW input power to the OPO. 3.57mW input power to OPO during the measurement
Common mode board gain (common path): -13dB
Boosts: 0Hz/10Hz, slow path 4Hz/400Hz
SHG loop
Calibration: 79mVpp measured at 1.8mW transmitted power
Comments: Low UGF because the loop inject (possibly) mechanical noise that shows up in CLF spectrum (alog52755). So far this hasn't been a problem.
Common mode board gain (common path): 7dB
Boosts: 0Hz/10Hz, slow path 4Hz/400Hz
TTFSS (Beckhoff control)
