Synchronization 7 Analog Modules
System Reference, January 2001

For a digitizer or sampler, you have to move the trigger
signal edge backward by the trigger line length plus the
trigger-to-signal delay from the reference point, then move
it forward by the signal line length. As a result, the digi-
tizer can start the measurement at the moment when the
analog signal arrives at the analog module pin.
