[Dsg-hallb_magnets] Scope Captures

[Amrit Yegneswaran]

oi, brian 
why am i looking at this? 
and what does this plot mean? 
is the baseline (carrier) level going up to 1.69 V. 
i assume these are from the VTs but which one. 
looks like the grounding scheme has to be revisited, if it is baseline shifts? 
whats the freq? 
let me know.

There is either a .png + .txt or .csv + .txt with the same filename (the number below corresponds to the number in the filename). 
The .txt file has the scope setting & statistics. 

0 = MPS on, set to 0A 
1 = Same, but finer time scale (so more points) 
2 = Ramping to 5A 
3 = XY points from same ramp 
6 = MPS set to 5A, steady state 
7 = ZFCT output from remote MPS chassis 

Let me know if there's any questions. 

We're in the process of increasing the threshold for QD #1 channels 1 & 2 to 100 mV
