11. Start a sweep.
The determined powers and limit deviations for each range are indicated in the
Result Summary. If activated, the peak power levels for each range are also indica-
ted in the Spectrum diagram.

To perform a Multi-SEM measurement
1. Define the span of the signal to be monitored in the general span settings.
2. Select the "Multi-SEM Config" softkey.
3. Define the number of sub blocks (up to 3) that contain the relevant carriers.
4. For each sub block, define the center frequency, that is, the frequency of the TX
carrier or a frequency in the dedicated reference range.
5. For each sub block, do one of the following:
● Select a standard settings file to be used.
● Select the "Edit" button and configure the sweep list manually as defined in
configure a user-defined SEM measurement"
on page 187. Be sure to select
the correct vertical tab for the corresponding sub block within each subtab of
the "Spectrum Emission Mask" configuration dialog.
Define a function to be used for overlapping ranges in the "Multi-Limit Calc"
field of the sweep list.
6. Start a sweep.
The determined powers and limit deviations for each sub block, each gap, and
each range are indicated in the Result Summary. If activated, the peak power lev-
els for each range are also indicated in the Spectrum diagram.
7. To save the Result Summary, export the results to a file as described in
How to Manage SEM Settings Files
SEM measurement settings can be saved to an XML file which can then be exported to
another application or loaded on the R&S
FPL1000 again later. Some predefined XML
files are provided that contain ranges and parameters according to the selected stan-
dard. All XML files are stored under
C:\ProgramData\Rohde-Schwarz\ZNL-FPL\sem_std
.
For details on the file format of the SEM settings file, see
