Push the
Help
button to display the Help menu. The topics cover all the menu
options and controls of the oscilloscope.
Horizontal
You can use the horizontal controls to adjust the trigger point location relative to
the acquired waveform and to adjust the horizontal scale (time/division).
A readout near the top right of the screen displays the current horizontal position
in seconds. 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 Delayed Sweep.
Push to center the trigger on the screen.
Horizontal Scale Knob (seconds/division).
Use to change the horizontal time scale
to magnify or compress the waveform.
Key Points
Horizontal Scale.
If waveform acquisition is stopped (using the
Run/Stop
or
Single
button), the
Horizontal Scale
control expands or compresses the
waveform. Use to zoom in on a detail of the waveform.
Scan Mode Display (Roll Mode).
When the
Horizontal Scale
control is set to
100 ms/div or slower and the trigger mode is set to Auto, the oscilloscope enters
the Scan acquisition mode. In this mode, the waveform display updates from left
to right. There is no trigger or horizontal position control of waveforms during
scan mode. (See page 71,
