4.11.5 Distributing level trigger
Multiple boards may be triggered by a level trigger on one channel in one of the digitizers. This mode is
intended for systems with a reference event on one channel that starts the acquisition on all channels.
It may also be used for designing a high precision trigger. The trigger event on channel D in
is recorded on the channel D. The trigger timing is then calculated with high precision using interpola-
tion.
