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
FSW again later. Some predefined XML files
are provided that contain ranges and parameters according to the selected standard.
All XML files are stored under
C:\Program Files (x86)\Rohde-Schwarz\FSW\<version>\sem_std
.
For details on the file format of the SEM settings file, see
SEM settings or standard files are managed in the "Standard" tab of the "Spectrum
Emission Mask" dialog box. To display this dialog box, select the "Overview" softkey
and then the "SEM Setup" button.
How to load an SEM settings file
1. From the file selection dialog box, select the settings file (with
a .xml
extension).
2. Select the "Load" button.
The settings from the selected file are restored to the R&S
FSW and you can
repeat the SEM measurement with the stored settings.
