Using the Oscilloscope
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 Control See figure 3-11. At the left side of the Horizontal and
Trigger toolbar bar are six icons:
• The leftmost is a blue-green octagon. Clicking this starts an acquisition.
(Same as pressing the [Run] key on the front panel.)
• The next control is a red octagon. Clicking this stops acquisition. (Same as
pressing the [Stop] key on the front panel.)
• The next control is a yellow octagon. Clicking this starts a single acquisition.
(Same as pressing the [Single] key on the front panel.)
• The next control is a small windshield wiper. Clicking this clears acquired
waveform data from the display. (Same as pressing the [Clear Display] key
on the front panel.)
• The next control is a printer. Clicking prints the screen to the default printer.
• 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 on 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
