Horizontal And Trigger Toolbar - Agilent Technologies 54831A User's Quick Start Manual

Using the Oscilloscope
Graphical Interface Mode
The top of the waveform display area includes the vertical settings and controls.
In full-screen mode, only channels that are turned on are shown, with the
corresponding vertical scaling settings in volts per division. When the graphical
interface is enabled, all channels are shown. Each has a checkbox allowing you
to turn that channel on or off, and a set of controls allowing you to change the
vertical scaling. Clicking directly on the vertical scaling value displays a pop-
up numeric keypad allowing you to set a precise vertical scale.

Horizontal and Trigger Toolbar

At the bottom of the waveform display area is the horizontal and trigger toolbar.
This includes the run/stop controls, the horizontal controls, and the trigger
controls.
Run/Stop Controls See figure 3-27. At the left side of the bar are three
icons:
• The leftmost is a blue-green octagon. Clicking on this starts an acquisition.
(Same as pressing the Run key on the front panel.)
• The middle is a red octagon. Clicking on this stops acquisition. (Same as
pressing the Stop key on the front panel.)
• The rightmost is a small windshield wiper. Clicking on this clears acquired
waveform data from the display. (Same as pressing the Clear Display key on
the front panel.)
Horizontal settings and controls The middle of the bar contains the
horizontal settings and controls. Leftmost is a button, labeled with an "H."
Clicking on this will display the horizontal setup dialog box.
Next is the current sweep speed. Clicking on this displays a pop-up numeric
keypad so you can set a particular sweep speed. Or, you can click on the two
icons to the right of the sweep speed setting to cycle through the preset speeds.
The leftmost icon shrinks the waveform, which decreases the sweep speed and
increases the time per division. The rightmost icon stretches the waveform,
which increases the sweep speed and decreases the time per division.
Next is the horizontal position (delay) setting. Clicking on this displays a pop-
up numeric keypad that allows you to 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.
