Looking at the ALS fiber distribution box:

• The external PD is saturating, needs an ND filter with a factor of 2-4 attenuation.
• The internal PD gain is set at 0dB, but should be 30dB (this also requires adjustments to the lower limit and normalization).

We have 15-20mW into the fiber. With a ~7% splitting ratio (the losses through the AOM are about 3 times higher than specifications would indicate), we will have about 1mW in the SQZ LO fiber output. This is in line with the L1 measurement in alog 28961.
