Recording time windows

The data logger's measurements are recorded in a time window, the duration of which is defined and synchronized by an event (trigger/stop
event) of your choice.
The following figure displays the time window, the trigger and the samples available in gray:
Samples
The user can select the sampling frequency (see par. 16.4.2.2), the type of stop event (trigger) (see par. 16.4.2.3) and the stopping delay (see
par. 16.4.2.4) so as to obtain the required pre-trigger with respect to the selected event.
Depending on the selection you make, the stopping delay may be nil, or it may be lower or higher than the recording time, as illustrated in the
following figure:
