Trigger position can set enter, exit and time. Select trigger position to confirm the timing of trigger.
a.
Enter
：
It will be generated when the input signal enter the specified trigger level.
b.
Exit
：
It will be generated when the input signal exit the specified trigger level.
c.
Time
：
It will be generated when the over-amplitude entered, accumulated hold time is greater than
or equal to the preset over-amplitude time.
(3) Trigger Setting
When trigger position is set to “Over-amplitude Time”, the setting time takes effect and triggered
when condition is met. The range can be set to 8ns ~ 10s.
(4) Level Setting
Level setting can set low level, high level and high-low level. Press LEVEL knob on trigger control area
to quickly switch the selection.
a. Low level
：
Adjust low level threshold of ramp trigger by using LEVEL knob on trigger control area.
b. High level
：
Adjust high level threshold of ramp trigger by using LEVEL knob on trigger control area.
c. High-low level
：
Adjust high-low level threshold of ramp trigger by using LEVEL knob on trigger control
area.
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 7-6.
Figure 7-6
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 7-6.
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.
