We began by misaligning ITMX. At which point our starting RF AM signal was -47dBm at 24.41MHz. We inserted a PBS before the EOM to ensure that we had optimized s-pol into the EOM. Then we adjustd the EOM stage such that the RF AM signal dropped to -60dBm. The Imon signal then had an RF AM offset of 2mV, with a peak-to-peak of 4mV at 500Hz (in comparison to alog 9434). The Qmon signal had an RF AM offset of 1mV with a peak-to-peak of 3mV.

We then examined the noise out of Imon with the cavity misaligned, and only saw a factor of 2 decrease at 100Hz compared to the previous measurement (alog 9436). This reduction could have also come from the improved modulation depth we achieved today. There is still too much noise...
