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) analysis of signals.
Press the HORIZONTAL Scale Knob on the front panel to turn on the zoom function,
and press the button again to turn off the function. When Zoom function is on, the
display divides in half. The top half of the display shows the normal time base
window and the bottom half displays a faster Zoom time base window.

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.
To change the time base for the Zoom window, turn the Horizontal Scale Knob. The
Horizontal Scale Knob controls the size of the box. The Horizontal Position Knob
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 of the display when the Horizontal Position Knob is turned. Negative
delay values indicate you're looking at a portion of the waveform before the trigger
