To define coupled zoom areas
You can define multiple zoom areas for one diagram that are coupled, i.e. if you change
the size of one zoom area, the size of all coupled zoom areas is changed as well. This
is useful, for example, if you want to compare recurring peaks in a signal.
1. On the toolbar, tap the "Coupled Zoom" icon.
2. In the diagram overview, select an existing zoom area.
The selected zoom area is duplicated.
3. Drag the duplicate zoom area to the required position.
4. To create further coupled zooms, repeat the steps above.
Now if you edit the zoom area size for any of the coupled zoom areas in the
"Zoom" dialog box (for example the range) or by dragging the edges on the touch
screen, the settings are changed for all of them.
To close the zoom diagram
► Tap the "Delete" icon on the toolbar, then tap the zoom diagram.
The diagram in the overview diagram returns to the original display size.
To use the hardware zoom
In contrast to the normal zoom, the hardware zoom changes the instrument settings -
horizontal and vertical scales, and also the trigger level and offset - to display the selected
area in the diagram instaed of the original waveform. No additional zoom diagram is
opened.
1. On the toolbar, tap the "Hardware Zoom" icon.

2. Drag your finger on the touch screen to mark the zoom area.
A dotted rectangle is displayed to indicate the current zoom area. When the rectangle
covers the required zoom area, remove your finger. The diagram changes and shows
the magnified area.
Tip: To return to the previous display, use the "Undo" icon.
Note: You can combine hardware zoom and normal zoom - first use the hardware
zoom, then the zoom into the display. The reverse approach is also possible: Create
a zoom diagram, and then apply the hardware zoom to the waveform diagram. Both
the waveform and the zoom diagrams are changed.
