Signal Conditioning

The hardware Trigger and EndTrigger signals issued from differential inputs are conditioned before being applied to the acquisition controller.

Each signal is sampled at a constant frequency of 50 MHz and flows through a digital filter.

With such a filter:

The following table shows for each possible value of the respective TrigFilter and EndTrigFilter parameters:
