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 7-13 .
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 7.6.5.4, "Power Classes" , on page 230. The child nodes and attributes of
this element are shown in Table 7-14 .
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-
ber of ranges is 30. Note that the R&S
FSV/A uses the same ranges in each power
class. Therefore, the contents of the ranges of each defined power class have to be
identical to the first power class. The
Start
and
Stop
values of the two
Limit
nodes
that are used to determine the power class are an exception. Note also that you must
define two limit nodes: one that defines the limit in absolute values and one in relative
values. Make sure units for the
Start
and
Stop
nodes are identical for each
Limit
node.
For details, refer to Chapter 7.6.5.1, " Sweep List " , on page 221. The child nodes and
attributes of this element are shown in Table 7-15 .
