So as we have been finalizing Vbias and the gate settings and so forth, I noticed that the first 4 channels have some odd behavior in the ADC plots. They are EPP1-4 TT1 (all on 1 daughter card, probably what is causing this). Pictures of ADC and TAC below. All of the recent runs are like this, even after rebooting the crate.

Figure 2. TACs for PP 1,2,3,4 TT1

From what I understand from Akio, the red on the ADC is the "out of time" signal. For all other channels, the red looks ~like a cutoff in low ADC (and you can see this on the plots included). Here it also extends out through the entire signal region, cutting out some percentage of good data. I would think since it's a timing issue it would be related to the TAC, but the TAC plots (also included) to my eye look fine and like every other channel.

We might need to replace this daughter card/QT card in the future. We should keep an eye on this.
