Today I updated the monitor filters for these new frequencies. Thanks Betsy for the nice table.
We have seen a couple of locklosses because of a rung up bounce mode when doing our low noise asc steps, changing the coil drivers, and transitioning to the low noise ESD all in rapid sucsession. The mode rings down very quickly, so we may just need to add a check on the monitor in some of these states and wait for the mode to ring down before we change the coil drivers.
I also added a check on the monitor that includes all the bounce modes in LOWNOISE_ASC, so that the guardian won't move on unless the monitor is below 2 (in arbitrary logarithmic units). The bounce mode wasn't rung up on our last lock, so we may still need to adjust the level of the check.
