List Evaluation (Result Summary) State
Activates or deactivates the Result Summary.
Remote command:
CALCulate<n>:ESPectrum:PSEarch|PEAKsearch:AUTO on page 760
TRACe<n>[:DATA] on page 922
Show Peaks
If activated, all peaks that have been detected during an active SEM measurement are
marked with blue squares in the Spectrum diagram.
Remote command:
CALCulate<n>:ESPectrum:PSEarch|PEAKsearch:PSHow on page 761
Margin
Although a margin functionality is not available for the limit check, a margin (threshold)
for the peak values to be displayed in the result summary (and diagram, if activated)
can be defined. Only peaks that exceed the margin value are displayed.
Remote command:
CALCulate<n>:ESPectrum:PSEarch|PEAKsearch:MARGin on page 761
Saving the Result Summary (Evaluation List) to a File
Exports the Result Summary of the SEM measurement to an ASCII file for evaluation
in an external application. If necessary, change the decimal separator for evaluation in
other languages.
Define the file name and storage location in the file selection dialog box that is dis-
played when you select the "Save" function.
For details see chapter 5.6.8.2, "ASCII File Export Format (Spectrum Emission Mask)",
on page 237.

5.6.6 How to Perform a Spectrum Emission Mask Measurement
SEM measurements can be performed according to a specific standard or freely con-
figured. Configuration for signals with a very regular channel definition can be config-
ured very quickly and easily. Selecting the SEM measurement is a prerequisite for all
other tasks. For multi-standard radio SEM measurements, configuration for specified
scenarios can be done automatically.
For signals with multiple carriers, also in non-contiguous ranges, an SEM measure-
ment with multiple sub blocks can be configured.
The following tasks are described:
●
"To select an SEM measurement" on page 226
●
"To perform an SEM measurement according to a standard" on page 226
●
"To configure a user-defined SEM measurement" on page 226
