can only interpret XML files of a known structure. For sample files, see the
C:\Program Files\Rohde-Schwarz\FSV3000\<version>\sem_std
directory
of the R&S FSV/A.
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 260).
All XML files are stored under
C:\Program Files\Rohde-Schwarz\FSV3000\<version>\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 FSV/A 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 5-12 .
Example:
In the sample file
PowerClass_39_43.xml
under
C:\Program Files\Rohde-Schwarz\FSV3000\<version>\sem_std\WCDMA\
3GPP
, these attributes are defined as follows:
●
Standard="W-CDMA 3GPP"
●
LinkDirection="DL"
●
PowerClass="(39,43)dBm"
The "PowerClass" element
It is embedded in the
BaseFormat
element and contains settings information about
the power classes. Up to four different power classes can be defined. For details, refer
to
Chapter 5.6.5.4, "Power classes" , on page 249. The child nodes and attributes of
this element are shown in Table 5-13 .
The "Range" element
This element is embedded in the
PowerClass
element. It contains the settings infor-
mation of the range. There have to be at least three defined ranges: one reference
range and at least one range to either side of the reference range. The maximum num-
Spectrum emission mask (SEM) measurement
