1. Tap the "Multiple Zoom" icon in the toolbar.
The icon is highlighted orange to indicate that multiple zoom mode is active.
2. Tap the diagram near the first peak and drag your finger to the opposite corner of
the zoom area. A white rectangle is displayed from the point where you tapped to
the current position.
Figure 5-15: Defining the zoom area
When you remove your finger, the zoom area is enlarged in a second (sub-)win-
dow.

3. In Figure 5-16 , the enlarged peak is represented by a very thick trace. This is due
to the insufficient number of sweep points. The missing sweep points for the
zoomed display are interpolated, which provides poor results. To optimize the
results, we will increase the number of sweep points from the default 1001 to
32001.
a) Press the [Sweep] key on the front panel.
b) Tap the "Sweep Config" softkey in the "Sweep" menu.
c) In the "Sweep Points" field, enter
32001 .
d) Press the RUN SINGLE key on the front panel to perform a new sweep with
the increased number of sweep points.
