Introduction to the Horizontal System   

Shown as 

Figure 3-11

, there are a button and two rotary controls in the 

Horizontal

 

Controls

. The following practices will gradually direct you to be familiar with the 

setting of horizontal time base.   

 

Figure 3-11 Horizontal Control Zone   

1.

 

Turn  the 

Horizontal Scale 

rotary control  to change the horizontal time base 

setting and observe the consequent status information change. Turn  the 

Horizontal Scale

 rotary control to change the horizontal time base, and it can be 

found that the 

Horizontal Time Base

  display in the status bar changes 

accordingly.   

2.

 

Use the 

Horizontal Position 

rotary control to adjust the horizontal position of the 

signal in the waveform window. The 

Horizontal Position 

rotary control is used 

to control the triggering displacement of the signal or for other special 
applications. If it is applied to triggering the displacement, it can be observed that 
the waveform moves horizontally with the rotary control  when you rotate the 

Horizontal Position

 rotary control.   

Triggering displacement back to 0 shortcut key 

Turn the 

Horizontal Position

 rotary control to change the horizontal position of 

channel and push the 

Horizontal Position

  rotary control  to set the 

triggering 

displacement

 back to 0 as a shortcut key. 

3.

 

Push the 

Horizontal HOR

 button to switch between the normal mode and the 

wave zoom mode.
