Note: In Window trigger, pressing Trigger    LEVEL can quickly switch the 
current level adjustment type.   
 
Rotate the Trigger    LEVEL knob to adjust the corresponding trigger level. 
During the adjustment of trigger level, two trigger level lines appear on the screen, 
and they move up and down with the change of the trigger level. At the same time, 
the real-time trigger level and slope information is displayed at the lower-left corner 
of the screen (as shown in the figure below, H indicates the upper limit of the trigger 
level, L indicates the lower limit of the trigger level, and  △  indicates the trigger level 
deviation). When you stopping modifying the trigger level, the trigger level line and 
the trigger level information at the lower-left corner of the screen disappear in about 
2 s. The current trigger level deviation is displayed at the upper-right corner of the 
screen. 
 
 
Trigger Mode: 
In the trigger control area (Trigger) on the front panel, press Mode to quickly switch 
the current trigger mode. For details, refer to descriptions in "Trigger Mode".

Delay Trigger 
 
In Delay trigger, you need to set Source A and Source B. The oscilloscope triggers 
when the time difference (△T) between the specified edges of Source A (Edge A) and 
Source B (Edge B) meets the preset time limit, as shown in the figure below. 
Note: Edge A and Edge B must be two neighboring edges.
