Chapter 3 Horizontal System Setting    RIGOL 
MSO4000/DS4000 User’s Guide  3-3 
To Adjust the Horizontal Position 
 
The horizontal position (also called trigger position) refers to the position of the 
trigger point of the waveform relative to the screen center in the horizontal direction. 
The horizontal position is positive (negative) when the waveform trigger point is at 
the left (right) of the screen center.  
 
Turning HORIZONTAL 
  POSITION can adjust the horizontal position of the 
channel waveform.  
  Turn the knob clockwise to reduce the horizontal position and counterclockwise 
to increase the horizontal position. 
  Pressing the knob can quickly reset the horizontal position to 0.  
 
When modifying the horizontal position, the trigger point and the waveforms 
displayed move left or right; the horizontal position information (as shown in the 
figure below) at the upper-right side of the screen changes accordingly.  
 
 
Note: When delayed sweep is turned on, HORIZONTAL 
  POSITION is used to 
adjust the delayed sweep horizontal position (pressing this knob can quickly reset 
the delayed sweep horizontal position); the delayed sweep horizontal position 
information (as shown in the figure above) at the upper-right side of the screen 
changes accordingly.
