Interval Greater Than: For this Interval Trigger, generated on an interval larger than the one that you set, select
a minimum interval between two edges of the same slope. The instrument generates the trigger on the second
edge if it occurs after the set interval. The timing for the interval is initialized and restarted whenever the selected
edge occurs.
Figure 4-21. Interval Trigger that triggers when the interval width is larger than the set interval. The
broken upward-pointing arrow indicates a potential trigger, while the bold one shows where the actual
trigger occurs — on the positive edge after the selected interval.
Interval In Range: This Interval Trigger is generated whenever an interval between two edges of the same slope
falls within a selected range. The instrument initializes and restarts the timing for the interval whenever the
selected edge occurs.
Figure 4-22. Interval Trigger that triggers when the interval falls within the selected range:
t
1
= range's lower time limit; t
2
= range's upper limit. The broken upward-pointing arrow indicates a
potential trigger, while the bold one indicates where the actual trigger occurs — on the positive edge
within the selected range.
