Zoom Mode
Zoom is a horizontally expanded version of the normal display. You can use Zoom to locate and
(horizontally) expand part of the normal window for a more detailed (higher-resolution) view.
Press
Shift and Clear Sweep on the front panel to turn on the zoom function, and press them again
to turn it off. When Zoom is on, the display window splits in half. The top half shows the main window
and the bottom half displays a faster (less time/div) zoom window.
Figure 14 Split Screen Zoom
The zoomed-in area of the normal window is outlined with a border, and the rest of the normal window
is shaded. The selected area is zoomed in on at the bottom of the screen.
To change the time base for the Zoom window, press
Horizontal Scale . The Horizontal Scale button
controls the size of the border area. The Horizontal Position button sets the left-to-right position of
the zoom window. The delay value, which is the time displayed relative to the trigger point, is
momentarily displayed in the upper-right corner when you press
Horizontal Position . Negative delay
values indicate you're looking at a portion of the waveform before the trigger event, and positive values
indicate you're looking at the waveform after the trigger event.
To change the time base of the normal window, turn off Zoom; then press
