Chapter 5 To Trigger the Oscilloscope    RIGOL

⚫  >:  triggers  when  the  time  difference  (△T)  between  the  specified  edges  of 
Source A and Source B is greater than the preset time lower limit. Press Lower 
to set the delay time lower limit in Delay trigger.   
⚫  <:  triggers  when  the  time  difference  (△T)  between  the  specified  edges  of 
Source A and Source B is smaller than the preset time upper limit. Press Upper 
to set the delay time upper limit in Delay trigger.   
⚫  <>:  triggers  when  the  time  difference (△T)  between  the  specified  edges  of 
Source A and Source B is greater than the lower limit of the preset time and 
smaller than the upper limit of the preset time. Press Upper to set the delay 
time upper limit in Delay trigger. Press Lower to set the delay time lower limit in 
Delay trigger.   
Note: The lower time limit must be smaller than the upper time limit. 
⚫  ><:  triggers  when  the time difference  (△T)  between  the  specified  edges  of 
Source  A  and Source  B  is  smaller  than  the  lower  limit  of  the preset  time or 
greater than the upper limit of the preset time. Press Upper to set the delay 
time upper limit in Delay trigger. Press Lower to set the delay time lower limit in 
Delay trigger.   
Note: The lower time limit must be smaller than the upper time limit. 
 
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". 
 
Trigger Parameter Setting: 
Set the trigger parameters (trigger holdoff and noise rejection) under  this  trigger 
type.  For  details,  refer  to  descriptions  in  "Trigger  Holdoff"  and  "Noise 
Rejection". 
 
Trigger LEVEL/Threshold Level: 
Rotate the Trigger    LEVEL knob to adjust the trigger level/threshold level. Refer 
to  "Trigger  LEVEL/Threshold  Level".  The  current  trigger  level/threshold  level 
value is displayed at the upper-right corner of the screen. 
 
 
Setup/Hold Trigger 
 
In Setup/Hold trigger, you need to set the clock source and data source. The setup 
time starts when the data signal passes the trigger level and ends at the coming of 
the specified clock edge; the hold time starts at the coming of the specified clock 
edge and ends when the data signal crosses the trigger level again, as shown in the 
figure below. The oscilloscope triggers when the setup time or hold time is smaller 
than the preset time.
