A.3.1 I/Q Parameter XML File Specification
The content of the I/Q parameter XML file must comply with the XML schema
RsIqTar.xsd available at: http://www.rohde-schwarz.com/file/RsIqTar.xsd.
In particular, the order of the XML elements must be respected, i.e. iq-tar uses an
"ordered XML schema". For your own implementation of the iq-tar file format make
sure to validate your XML file against the given schema.
The following example shows an I/Q parameter XML file. The XML elements and attrib-
utes are explained in the following sections.
Sample I/Q parameter XML file: xyz.xml
