The first interval timer can be compared to the trigger hold off feature described
above. The second interval timer defines a period in which a trigger event must
occur. If not, it is not a related trigger event.

NotBetween
The inverse function of the Between mode of the interval timer is the
NotBetween mode. The second interval is not used to define a trigger
-
safe area,
but to denote a trigger
-
restricted area. A trigger event within the first interval is
valid. A trigger event within the second interval resets the trigger logic. A trigger
is also generated when both interval timers expire. A typical use of this mode
is to detect changes in the interval between pulses ("too early" / "too late"
detection).

The following sequence explains how this mode functions:
1 The first trigger event starts Interval Timer 1.
2 Interval 1
3 If a trigger event occurs within the first interval, a trigger is generated.
4 End of sweep.
5 The first new trigger event starts Interval Timer 1.
6 Interval Timer 1 expires and Interval Timer 2 is started.
7 A trigger event occurs within the second interval. Interval Timer 1 is
restarted.
8 Interval 2
9 Interval Timer 1 expires and Interval Timer 2 is started.
10 Interval Timer 2 expires and a trigger is generated.
