7.1.2.3 Display Functions
The graphical display provides general display functions known from other measure-
ment instruments and offers zoom and markers.
Zooming
You can zoom into the diagram to visualize the measurement results in greater detail.
Using the touchscreen or a mouse pointer you can easily define the area to be
enlarged.
Zooming is merely a visual tool, it does not change the number of samples used for the
calculation. You can increase the number of samples before zooming.
See also "To zoom into a diagram" on page 424.
Using markers
Markers are tools for numerical readout of measured data in diagrams. They help you
analyze the displayed signal characteristics by determining particular values in the dia-
gram.
Often you can use markers to measure the frequency distance of two peaks or to mea-
sure the power decrease of an oscillator at a given frequency offset, dBc value. Note
that markers in the diagram are not related to the markers in the digital standards.
