Dave and Alex, Using Mark's full list of 64 fast channels which should be acquired by the DAQ we increased L1QTS.ini from 25 chans to the required 64 chans. All fast channels are being acquired at 2048Hz. We attempted to turn on the second and minute trends, but found that starting minute trends crashed the DAQ. Alex took a look at the code, but was unable to find the cause. So for now, we are only acquiring full frame and second trends. I did the math, and figured that with the disk space available we can have: 14 days of second trends 11.5 days of full data We can extend the second trend look back at the expense of full frames if this is required. The DAQ was restarted many times between 17:30 and 18:30 for this work.
