• The rightmost control is the waveform brightness control.
Horizontal settings and controls The middle of the Horizontal and Trigger
toolbar contains the horizontal settings and controls. Leftmost is a button,
labeled with an "H." Clicking this displays the horizontal setup dialog box.
Next is the current horizontal scale. Clicking this displays a pop- up
numeric keypad so you can set a particular horizontal scale. Or, you can
click the two icons to the right of the horizontal scale setting to cycle
through the preset speeds. The left icon shrinks the waveform, which
decreases the horizontal scale and increases the time per division. The
right icon stretches the waveform, which increases the horizontal scale
and decreases the time per division.
Next is the horizontal position (delay) setting. Clicking this displays a
pop- up numeric keypad that lets you set a particular position. Or, you can
use the three icons to the right. The left arrow moves the waveform to the
left, the center "0" resets the delay to zero, and the right arrow moves the
waveform to the right.
Across the toolbar are three vertical arrows. These are the left, center, and
right horizontal reference indicators. Clicking one of these arrows moves
the horizontal position to the respective horizontal reference position on
the display—left, center, or right. Assuming the horizontal position is at
zero:
• Left means the information on the display is all post- trigger.
• Center means the information to the left of center is pretrigger; to the
• Right means the information on the display is pretrigger.
The horizontal position value represents the time relative to the trigger at
the respective horizontal reference. When you change the horizontal scale,
the waveforms expand and contract about this reference position.
Trigger settings and controls The right side of the Horizontal and Trigger
toolbar contains the trigger settings and controls. These will vary
depending on the current trigger configuration, which can be set using the
front panel and the graphical interface. Advanced trigger configuration
items are available only through the graphical interface. You can click the
button labeled with a "T" to bring up the trigger setup dialog box.
When the scope is set for edge trigger on a particular channel, the trigger
level setting is shown. You can click it to display a pop- up numeric keypad
that lets you set a particular trigger level. You can also click the up and
down arrows to the right of the setting to increase or decrease the trigger
