Acqiris SA240P User's Manual 55
Pre- and post-trigger delay
Description
To increase trigger flexibility, a pre- or post-trigger delay can be applied to the trigger position.
The pre-trigger is not supported in Averager mode or when in combination with one of the
following features: baseline stabilization, zero suppress (ZS1), data inversion capability or
simultaneous acquisition and readout (CST).

Trigger delay parameter
Digitizer acquisition mode
The amount of pre-trigger delay can be adjusted between 0 and 100% of the acquisition time
window, thus the minimum trigger delay is given by:
-1 * Record size / SamplingRate
The maximum post-trigger delay is given, respectively in sample or seconds by:
(2
24
– 1) *16 (in samples)
