This morning I tried turning off L2L3LP in FM6 slot of the L2 DRIVEALIGN filter bank. This immediately caused a lockloss. I later realized that I forgot to manually bring the gain (H1:SUS-ETMX_L2_DRIVEALIGN_L2L_GAIN) down to 0 before toggling FM6. I'm pretty sure this caused the lockloss because the time lines right up with my filter change (see attached). Next time I'll be sure to ramp the gain down between filter changes.



Lockloss UTC time was 2023-12-05 16:09:09Z
