40 Agilent Infiniium 90000 X-Series Oscilloscopes User’s Guide

Using the Oscilloscope

The horizontal scale and horizontal position controls now change how

the waveform is shown in the delayed sweep window. The horizontal

scale will change the amount of magnification, while the position will

change the part of the waveform in the main window that is shown in

the zoomed window.

• Press the [Zoom] key again to turn it off.

Setting the horizontal reference point

• Click one of the three vertical arrows in the horizontal and trigger

toolbar to set 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 post- trigger; center means the information to the left of center is

pre- trigger and to the right is post- trigger; and right means the

information is pre- trigger.

• A non- zero horizontal position value is the time relative to the trigger

event at the selected horizontal reference point.

Using the Horizontal Setup dialog box

• You can use the Horizontal Setup dialog box to set scale, position, and

the horizontal reference. You can also set up the delayed time base

window, which presents a magnified view of an area of the waveform.

To access the Horizontal Setup dialog box, click the in the

Horizontal and Trigger toolbar, or choose Setup > Horizontal from the

menu.
