options and controls of the oscilloscope. (See page xvi, Help System.)
Horizontal
You can use the horizontal controls to set up two views of a waveform, each with
their own horizontal scale and position. The horizontal position readout shows
the time represented by the center of the screen, using the time of the trigger
as zero. When you change the horizontal scale, the waveform will expand or
contract around the screen center.

waveform

NOTE. You can push the horizontal option buttons to switch between an entire
waveform display and a zoomed part of it.
A readout near the top right of the screen displays the current horizontal position
in seconds. An M indicates the Main time base and a W indicates the Window
time base. The oscilloscope also indicates horizontal position with an arrow icon
at the top of the graticule.
Knobs and Buttons
Horizontal Position knob. Use to control the position of the trigger relative to
the center of the screen.
The trigger point can be set to the left or the right of the center of the screen. The
maximum number of divisions to the left depends on the Horizontal Scale (time
base) setting. For most scales, the maximum is at least 100 divisions. Placing the
trigger point off the screen to the left is called D elayed Sweep.
SettoZerobutton. Use to set the horizontal position to zero.
Horizontal Scale knob. Use to change the horizontal time scale to magnify or
compress the waveform.
