7.2 Detailed Programming Examples
7.2.1 Default Settings of the R&S ESU
The following settings provide typical examples of how to change the default settings of the
R&S ESU.
Note that only some of the settings are necessary depending on the application example. In
many cases, it is not necessary to set resolution bandwidth, video bandwidth and sweep time
since these parameters are automatically calculated in the default setting when the span is
changed. Likewise, the input attenuation is automatically calculated in the default setting as a
function of the reference level. Last of all, the level detectors are linked to the selected trace
mode in the default setting.
The settings automatically calculated in the default setting are indicated with an asterisk (*) in
the following program example.
