To display the zoomed time base
Zoom, formerly called Delayed sweep mode, is a horizontally expanded version of
the normal display. When Zoom is selected, the display divides in half. The top
half of the display shows the normal time/div window and the bottom half
displays a faster Zoom time/div window.
The Zoom window is a magnified portion of the normal time/div window. You can
use Zoom to locate and horizontally expand part of the normal window for a more
detailed (higher-resolution) analysis of signals.
To turn on (or off) Zoom:
1 Press the zoom key (or press the [Horiz] key and then the Zoom softkey).
The area of the normal display that is expanded is outlined with a box and the rest
of the normal display is ghosted. The box shows the portion of the normal sweep
that is expanded in the lower half.
