The signal read by this ADC channel is now a copy of the integration gate, and will be used for rechecking the VQWK integration ranges for different helicity board settings.
The "MULTSYNC" diagnostic signal had been coming from the output of channel 8 of the center level translator of the INJ DAQ NIM crate.
The integration gate signal is now coming from the fourth logic channel of the left-most logic fan-out in the NIM crate; this is the same location which feeds the VQWK gate start signals.
Before switching these channels for use by the photodiodes, we will need
to take some data at the different T_stable and oversample combinations
we would want. And we'll need to adjust the VQWK integration windows
during these runs.
