7.8 Delay Trigger
Delay trigger should set trigger source 1 and trigger source 2. When the time difference (
△
T) between
the edge set by source 1 (edge 1) and the edge set by source 2 (edge 2) meets the preset time limit, the
oscilloscope is triggered, as shown in Figure 7-5.
Figure 7-5
Edge 1 set as rising edge, edge 2 also set as rising edge.
△
T is the area marked by red color, as shown
in Figure 7-5.
Note
：
Edge 1 and edge 2 must be adjacent edges .
Note
：
Only the channel that has been connected to the signal, select it as the trigger source that can get
the stable trigger.

a.
＞：
It will be generated when the time difference (
△
T) between the edge of source 1 and the
edge of source 2 is greater than the setting lower limit of time, it can set the lower limit of time.
b.
＜：
It will be generated when the time difference (
△
T) between the edge of source 1 and the
edge of source 2 is smaller than the setting upper limit of time, it can set the upper limit of
time.
c.
≤≥：
It will be generated when the time difference (
△
T) between the edge of source 1 and
the edge of source 2 is greater than the setting lower limit of time and smaller than the setting
upper limit of time, it can set the upper limit and lower limit of time.
d.
＞ ＜
( irrelevance)
：
It will be generated when the time difference (
△
T) between the edge of
source 1 and the edge of source 2 is smaller than the setting lower limit of time or greater than
the setting upper limit of time. It can set the upper limit and lower limit of time.
