Zooming in on the Waveform Horizontally «For procedures, see section 8.5.»
The displayed waveform can be expanded along the time axis. This function is useful
when the waveform acquisition time is set long and you want to observe a particular
section of the waveform closely. Zooming is not possible if the number of displayed
points on the screen is less than or equal to 10 (less than or equal to 50 for FFT
waveforms). The zoom position is set in units of divisions of the grid.
Display Format When the Waveform Is Zoomed
Zoomed waveforms of two locations can be displayed simultaneously (dual zoom).
Below are the combinations of the display methods of zoom waveforms.
Main:
Main waveform display frame
Z1, Z2:

<Main>
<Z1> or <Z2>
<Main>
<Z2>
<Z1>
<Z1>
<Z2>
<Z1> or
<Z2>
When displaying Main (main waveform) and Z1 or Z2 (zoomed waveform)
simultaneously, a zoom box indicating the zoom position is displayed within the main
waveform display frame. The center of the zoom area corresponds to the center of the
zoom box.

Auto Scroll
The zoom box automatically moves (scrolls) in the specified direction. You can scroll
while viewing the expanded waveform.
