Today I discovered FastSEE BPM light mode will let you select pass while still in auto select! that means all of these waveforms are available without disrupting any lock operations. Any oscillation up to 3.5 KHz can be localized to an Arc.

Wonderful news aside, A magnet seems to be shaking between IPM7A04 and IPM8E01 at 265 Hz vertically in an intermittent fashion. No suspected magnets yet.

We got a raster FSD trip and looked into what could cause it. The B raster X coil's peak current has gotten fairly noisy at the 5th pass setpoint.
