In light of yesterday's realization that POPAIR_B was saturating, and that DRMI locks much faster with a lower input power, here is a time series of the demodulated REFLAIR_A error signals during a DRMI lock acquisition attempt at 4 W.

The ADCs have a range of ± 2¹⁵ counts (≈ 33 000 counts). The largest excursions shown are something like 17 000 counts on RF9I, so that means at 10 W we would instead expect excursions of ≈ 43 000 counts, which means we'd be saturating.

The PRCL trigger is not shown in the attached plot, because PRCL is always on during locking.
