To find the optimal ADF demod phase for ADF servo, we scanned the ADF demod phase with ADF servo running, without SQZ ASC. The command to scan we used is as follows. We scanned the ADF demod phase from 72 to 92 deg. +2 deg and 120s delay time for each step, 10 steps in total.

ezcastep H1:SQZ-ADF_OMC_TRANS_PHASE -s '120' '+2,10'

The attached figure shows that the nominal ADF demod phase of 80 deg is already optimal value. So we left the ADF demod phase as it is.
