Power Measurements – MEAS Key R&S FSL

1300.2519.12 4.84 E-11

– Standard="W–CDMA 3GPP"

– LinkDirection="DL"

– PowerClass="(39,43)dBm"

• The second element is the PowerClass element, which is embedded in the BaseFormat element. It

carries settings information about the power classes. Up to four different power classes can be

defined. For details refer to the Sweep List softkey and the corresponding parameter description.

The child nodes and attributes of this element are shown in Table 4-6.

• The third element is the Range element, which in turn is embedded in the PowerClass element. It

carries the settings information 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 number

of ranges is twenty. Note that the R&S FSL 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 amd 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 the Sweep List softkey and the corresponding

parameter description. The child nodes and attributes of this element are shown in Table 4-7.

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 FSL 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 FSL 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

Base Format 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 Base Format element is structered as follows:

<RS_SEM_ACP_FileFormat Version=”1.0.0.0”>

<Name>Standard</Name>

<Type>Instrument Type</Type>

<Application>Application</Application>

</Instrument>

<Method>Method</Method>

</ReferencePower>

<!—- For contents of the PowerClass node see

Table 4-6 -->
