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 displayed 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.

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.
