t Time line
When a trigger event occurs, the start trigger (a) trips a fault record.
The first part of the recording records the signal profile before the trigger event (Pre-trigger time). After-
wards, the fault (a) to (b) is recorded. To evaluate the signal behavior even after the failure, the further signal
profile up to the end of the post-trigger time (c) is registered.
Trigger with Maximum Record Time
The maximum record time is used for the limit of the fault-record length.
