Front-end information¶

V1742 Digitizer¶

Post-Trigger¶

The V1742 has a register named POST_TRIGGER. This value is a percentage of the readout that is to be after the trigger. There is an implicit latency of around 40 ns, so in reality, the Post-Trigger percentage sets the percentage of the readout that will be after 40 ns past the trigger.

For an unknown reason, only certain values of POST_TRIGGER are accepted and must be found by trial and error.
