Format Description of SEM XML Files
The SEM XML files offer a quick way to change the measurement settings. A set of
predefined XML files for different standards is already provided. You can also create
and use your own XML files. Alternatively, edit the settings directly in the "Spectrum
Emission Mask" dialog box and save the XML file afterwards. This way, you do not
have to modify the XML file itself.
In addition to saving the current settings to a file, settings files can also be created
independently of the R&S
FPL1000, in an external application. When creating your
own XML files, be sure to comply with the following conventions because the
R&S
FPL1000 can only interpret XML files of a known structure. For sample files, see
the
C:\ProgramData\Rohde-Schwarz\ZNL-FPL\sem_std
directory of the
R&S FPL1000.
To load a settings file, use the "Load" function in the "Standard Files" tab of the "Spec-
trum Emission Mask" dialog box (see
"How to load an SEM settings file" on page 190).
All XML files are stored under
C:\ProgramData\Rohde-Schwarz\ZNL-FPL\sem_std
.
The files for importing range settings obey the rules of the XML standard. The child
nodes, attributes, and structure defined for the data import are described here.
Be sure to follow the structure exactly as shown below or else the R&S FPL1000 is not
able to interpret the XML file and error messages are shown on the screen. It is recom-
mended that you make a copy of an existing file and edit the copy of the file.
Basically, the file consists of three elements that can be defined:
●
The
BaseFormat
element
●
The
PowerClass
element
●
The
Range
element
The "BaseFormat" element
It carries information about basic settings. In this element, only the
ReferencePower
child node has any effects on the measurement itself. The other attributes and child
nodes are used to display information about the Spectrum Emission Mask standard on
the measurement screen. The child nodes and attributes of this element are shown in
Table 7-13 .
