Horizontal
You can use the horizontal controls to change the horizontal scale
and position of waveforms. The horizontal center of the screen is the
time reference for waveforms. Changing the horizontal scale causes
the waveform to expand or contract around the screen center.
Horizontal position changes the point, relative to the trigger, where
the waveform appears on the center of the screen.
