- from the patch there are two sets of signals that go to the V792 QDC:
1. The ADC cables. (ribbon cables) Approx. 170ns 2. The lead glass trigger cables. They are processed through a discriminator and a sequence of logic units followed by a short delay and then the translator. It is then connected to the V792 by a ribbon cable. The signal reaches the V792 QDC about 20-30ns before the ADC cables.
