6.1 Zoom
The zoom magnifies a part of the waveform to view more details. The zoom is applied
to all active analog and digital channels and math waveforms.
The following zoom types are available:
●
Horizontal zoom: the waveforms are displayed with a shorter time scale while the
vertical scale remains unchanged.
●
Vertical zoom: the zoom waveforms are enlarged in vertical and horizontal direc-
tion.
6.1.1 Zooming in
When you activate the zoom, two windows are displayed: the original waveform dia-
gram at the top, and the zoom window at the bottom.
► To activate the horizontal zoom, press the [Zoom] key.
► To activate the vertical zoom:
a) Tap the "Zoom" icon on the toolbar.
b) Drag you finger on the screen to draw the diagonal of the zoom area. A rectan-
gle indicates the current zoom area.
