- Lock IMC
- 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.
