7.1 Zoom
The zoom functions allow you to magnify a specific section of the diagram in order to
view more details. You can define several zoom areas for the same diagram and even
couple them, or you use the hardware zoom.
7.1.1 Methods of zooming
The R&S RTE provides various ways of zooming: You define the section of a diagram
that you want to magnify, and the zoomed view is shown in a separate zoom diagram.
Additionally, you can magnify the diagram directly: The hardware zoom changes the
horizontal and vertical scales of the diagram so that you see the selected section.
There are different ways to initiate and configure the zoom function:
●
Fingertip zoom: magnifies the waveforms around your fingertip. When you drag
your finger, the magnifier moves, too. You can convert the fingertip zoom into a
standard zoom diagram.
●
Graphical method: you draw, move and adjust the zoom area on the touchscreen
– a very quick and simple method for standard zoom and hardware zoom.
●
Numeric method: you enter x- and y-values in a dialog box or adjust them using
navigation controls. These are precise ways which can be used to optimize a
graphically defined zoom.
With the numeric method there are two ways of defining the zoom area:
– Specifying start and stop values for the x- and y-axes; the acquired data
within those values is zoomed.
