The feature is most useful in combination with the interval timer and/or the event
counter.
10.4.4 Interval timer
A highly sophisticated trigger add
-
on is the interval timer. The interval timer is
used to define a time relation between two trigger events. When the time
relation is correct, a trigger is generated.
The following relations are possible:
l
Less: The time interval between two consecutive trigger events is less than
the specified time interval.
l
More: The time interval between two consecutive trigger events is more
than the specified time interval.
l
Between: The time of the second trigger event is within a specified time
interval that starts a specified time after the first trigger event.
l
NotBetween: The time of the second trigger event is not within a specified
time interval that starts a specified time after the first trigger event.
The interval timer operates on samples (2 to 65535). In the Perception software,
this is translated into time. At 1 MS/s sample rate, this results in a maximum of
65.535 millisecond.

This interval time mode is fairly straightforward. When the second trigger event
is within the set time interval, a trigger is generated.
