Following up on Evan's investigation into the glitches from LL coil on the PRM M3. I tried to monitor the output with a scope attached. I was not looking for very big signals as the the noisemon indicated roughly 30mV signal and it has some gain associated with it. So I connected to scope probes to the LL coil drive signal and looked at it on a scope with a trigger set fairly low.(10s of milivolts). I also looked at UL just for comparison. I was able to get the signal to trigger on some events on LL that were not seen at as high a level on UL. This was with the DAC both connected and disconnected with small offset (20 counts) applied and a large offset (20,000 counts) applied. After a couple of hours of investigation I decided there were some glitches present and seemed to be from the coil driver not the DAC. I also looked at the DAC input to the coil driver and did not see the glitches. In the end I swapped out the coil driver. I am not 100% certain this will fix the problem as it was difficult to verify the glitches were present at all times.
