Jeff, Oli

Following up on one of Jeff's followup tasks about the signs of RM1 and RM2 (84462):

"(II) Measure the amplitude spectral density of each individual OSEMs well above the data rate we typically store them; look to see if there's no giant noise features. If there is -- debug that (usually a reboot of the satamp is the first step.)"

I ran ASD measurements for RM1 and RM2 at OSEMINF_OUT for each OSEM (with the comb60 filter turned off), and we verified they all look good(attachment1). To further check and compare them, we reran the same template (and filter) setup but for OM1 and OM2(attachment2). Since doors are currently being put on and the HAM1 ISI isn't isolated yet, we can see that the RM OSEM spectrum are very noisy below 30 Hz due to seismic noise, and other noises caused by the immediate environment are causing peaks at several different frequencies for thre RMs as compared to the OMs, but overall all four suspensions' OSEMs asymptote the same way and there aren't any noise features that seem to be of concern.
