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 filename and storage location in the file selection dialog box that is dis-
played when you select the "Save" function.
For details, see "ASCII File Export Format (Spectrum Emission Mask)" on page 198.

7.2.7.6 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 regular channel definition can be configured
quickly and easily. Selecting the SEM measurement is a prerequisite for all other tasks.
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 187
●
"To perform an SEM measurement according to a standard" on page 187
●
"To configure a user-defined SEM measurement" on page 187
●
"To perform a Multi-SEM measurement" on page 189
For remote operation, see Chapter 11.6.7.10, "Example: SEM Measurement",
on page 685.
To select an SEM measurement
► Press the [MEAS] key, then select the "Spectrum Emission Mask" measurement.
To perform an SEM measurement according to a standard
► Load the settings file as described in "How to load an SEM settings file"
on page 190 and start a measurement.
To configure a user-defined SEM measurement
1. Define the span of the signal you want to monitor in the general span settings.
2. Split the frequency span of the measurement into ranges for signal parts with simi-
lar characteristics.
Starting from the center frequency, determine which sections of the signal to the
left and right can be swept and monitored using the same parameters. Criteria for
such a range definition may be, for example:
● The signal power level
