Abstract:

I measured OLTF of DARM, MICH, PRCL, and CARM at PRFPMI_RF_LOCKED state.
Since MICH gain was reduced by 3dB, I increased the gain at FM2 of MICH2 filter bank.

Detail:

I measured OLTF of DARM, MICH, PRCL, and CARM, respectively.
Since MICH OLTF was 3dB smaller than before, so I increased the gain of MICH at FM2 of MICH2 filter bank (fig1).

Figure 2-5 show the OLTF of DARM, MICH, PRCL, and CARM, respectively after gain tuning.
Note that I just measured around UGF to save the time and DARM OLTF measurement result is only above UGF due to the lockloss during the measurement.

DARM gain is 1dB higher but it is acceptable, so I keep this condition.
PRCL OLTF shape seems different from reference maybe due to the filter changes (klog33437).
CARM UGF is 45kHz and phase margin is enough large.
Since CARM UGF will be adjusted at INCREASE_LAS_POWER state, this condition is acceptable at this moment.
