Format Description of Spectrum Emission Mask XML files
The files for importing range settings are in XML format and therefore obey the rules
of the XML standard. Below, the child nodes, attributes, and structure defined for the
data import is described. Build your own XML files according to these conventions
because the instrument can only interpret XML files of a known structure. For exam-
ple files look in the
D:\r_s\instr\sem_std folder.
Basically, the file consists of three elements that can be defined.
• The first element of the structure is 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 4-3 .
In the example above ( PowerClass_31_39.xml under
D:\r_s\instr\sem_std\WCDMA\3GPP ),
these attributes are defined as follows:
Standard="W-CDMA 3GPP"
LinkDirection="DL"
PowerClass="(31,39)dBm"
• The second element is the PowerClass element, which is embedded in the
BaseFormat element. It carries settings information about the power classes. The
child nodes and attributes of this element are shown in
Table 4-4 .
It is mandatory to follow the structure exactly as shown below or else the analyzer
is not able to interpret the XML file and error messages are shown on the screen.
For this reason is it recommended to make a copy of an existing file and edit the
copy of the file. The default files can be found in the
D:\r_s\instr\sem_std folder.
