Explanation of Functions

Zooming in on the Waveform Horizontally <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 wish to observe a particular
section of the waveform in detail. 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 display methods of zoom waveforms.
Main:
Main waveform display frame
Z1, Z2: Zoom waveform display frame
<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.

Snapshot <Section 8.7>
When the trigger mode is set to a mode other than single, the displayed waveforms are
periodically updated or displayed in roll mode.
By using the snapshot function, you can temporarily hold the waveform that would be
cleared when the screen is updated (snapshot waveform) on the screen. The snapshot
waveform is displayed in white, allowing for easy comparison against the updated
waveform. The snapshot waveform is a screen image waveform. You can save, load,
and print the screen image data, but cursor measurements, automated measurement of
waveform parameters, zoom, and computation cannot be performed on it.
