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. 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 251. The child nodes and
attributes of this element are shown in Table 7-16 .
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. The
hierarchy of the XML cannot be seen in the tables. View one of the predefined files
already stored on the R&S
FSW in the "
C:\Program Files
(x86)\Rohde-Schwarz\FSW\<version>\sem_std
" directory, or check the struc-
ture 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. They must be inserted where
noted. They are separated here simply to provide 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:
– <RS_SEM_ACP_FileFormat Version="1.0.0.0">
<Name>"Standard"</Name>
<Instrument>
<Type>"Instrument Type"</Type>
<Application>"Application"</Application>
</Instrument>
<LinkDirection Name="Name">
<ReferencePower>
<Method>"Method"</Method>
</ReferencePower>
<PowerClass Index="n">
<!-- For contents of the PowerClass node, see
Table 7-15 -->
<!-- Define up to four PowerClass nodes -->
</PowerClass>
</LinkDirection>
</RS_SEM_ACP_File>
●
The "PowerClass" element is structured as follows:
–
<PowerClass Index="n">
<StartPower Unit="dBm" InclusiveFlag="true" Value="StartPowerValue"/>
<StopPower Unit="dBm" InclusiveFlag="false" Value="StopPowerValue"/>
<DefaultLimitFailMode>"Limit Fail Mode"</DefaultLimitFailMode>
<Range Index="n">
<!-- For contents of the Range node, see
Table 7-16 -->
<!-- Define up to twenty Range nodes -->
</Range>
