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.
(1) Condition
Set delay condition to ＞, ＜, ＜＞, ≤≥, ＞＜ .
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.
