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
FSW 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. An exception are the Start and Stop values of the two
Limit nodes that are used to determine the power class. Note also, that there are two
Limit nodes to be defined: one that gives 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
on page 209. The child nodes and
attributes of this element are shown in
The following tables show the child nodes and attributes of each element and show if a
child node or attribute is mandatory for the R&S
FSW to interpret the file or not. Since
the hierarchy of the XML can not be seen in the tables, either view one of the default
files already stored on the R&S
FSW in the "
C:\r_s\instr\sem_std
" directory or
check the structure as shown below.
Below, a basic example of the structure of the file is shown, containing all mandatory
attributes and child nodes. Note that the "PowerClass" element and the range element
are themselves elements of the "BaseFormat" element and are to be inserted where
noted. The separation is done here simply for reasons of a better overview. Also, no
example values are given here to allow a quick reference to the tables above. Italic font
shows the placeholders for the values.

The "BaseFormat" element is structured as follows:
–

<!-- Define up to four PowerClass nodes -->

The "PowerClass" element is structured as follows:
