Zoom sweep is an expanded version of main sweep. When Zoom
mode is selected, the display divides in half and the Zoom
sweep icon displays in the middle of the line at the top of the
display. The top half of the display shows the main sweep and
the bottom half displays the Zoom sweep.
Zoom sweep is a magnified portion of the main sweep. You can
use Zoom sweep to locate and horizontally expand part of the
main sweep for a more detailed (higher-resolution) analysis of
signals.
The following steps show you how to use Zoom sweep. Notice
that the steps are very similar to operating the "delayed sweep"
in analog oscilloscopes.
1 Connect a signal to the oscilloscope and obtain a stable
display.
2 Press Menu/Zoom.
3 Press the Zoom softkey.
To change the sweep speed for the Zoom sweep window, turn
the sweep speed knob. As you turn the knob, the sweep speed is
highlighted in the status line above the waveform display area.
The area of the main display that is expanded is intensified and
marked on each end with a vertical marker. These markers show
what portion of the main sweep is expanded in the lower half.
The Horizontal knobs control the size and position of the Zoom
sweep. The delay value is momentarily displayed in the
upper-right portion of the display when the horizontal position
( ) knob is turned.
To change the sweep speed for the main sweep window, press
the Main softkey, then turn the sweep speed knob.
