2.6 Display
Waveform
Zooming ►For the procedure, see section 8.1
Displayed waveforms can be enlarged in both the time axis and the voltage axis
directions. This function is useful when the signal acquisition time is set long and you
wish to observe a particular section of the waveform closely. The zoom position can be
set in grid div units.
The zoom waveform can be displayed at up to two positions simultaneously (dual zoom).
The display combinations of the normal waveform, zoom waveform, and analysis screen
windows are as follows, with the normal waveform area identified as Main, the zoom
waveform areas as Z1 and Z2, and the analysis areas as A1 and A2.

When the Main (normal waveform) and Zoom 1 or Zoom 2 waveforms are displayed
simultaneously, a zoom box appears in the normal waveform area to indicate the zoom
position. The center of the zoom is the center of this box. For details of display examples,
see section 1.3, “Screen Displaying Zoom Waveforms.”
You can select the display format of the zoom waveform area, and whether a trace is on
or off, independently of the Main waveform area.
When zooming in the voltage axis direction, you can select a waveform to enlarge, and
set it to 1.05 to 10 times normal size.
When zooming in the time axis direction, you can enlarge until there are ten data points
in the zoom waveform area.
You can also set a point meeting a set trigger condition as the zoom center, or
automatically move the zoom center.
