You can define in which detail the data is displayed in the result summary in the "List
Evaluation" settings (see
Chapter 7.6.5.7, "List Evaluation (Results Configuration)" ,
on page 265). By default, one peak per range is displayed. However, you can change
the settings to display only peaks that exceed a threshold ("Margin").
Detected peaks are not only listed in the Result Summary, they are also indicated by
colored squares in the diagram (optionally, see
Show Peaks in the "List Evaluation"
settings).

Furthermore, you can export the results of the result summary to a file which can be
exported to another application for further analysis.
Results for SEM with multiple sub blocks
In the Spectrum application only, spectrum emissions can be measured for multiple
sub blocks of channels (see
Chapter 7.6.4.5, "SEM with Multiple Sub Blocks ("Multi-
SEM")" , on page 246 for details). Up to 8 sub blocks (with 7 gaps) can be defined. For
each sub block and each gap, the results described above are provided individually in
the result summary.
