Q Measurement of Test Masses
Lock one of the arms (only) using the IR PDH signal feeding back to an ETM.
Excite the ITM using the SR785 near 28.8 kHz
Look for the resulting peak using the SR785 spectra of the POX or POY error signal from the demod board
Based on the calibrated noise level of the POX/POY, estimate what the SNR will be of the internal mode peak.
