Contained files

An iq-tar file must contain the following files:

●

I/Q parameter XML file, e.g. xyz.xml

Contains meta information about the I/Q data (e.g. sample rate). The filename can

be defined freely, but there must be only one single I/Q parameter XML file inside

an iq-tar file.

●

I/Q data binary file, e.g. xyz.complex.float32

Contains the binary I/Q data of all channels. There must be only one single I/Q

data binary file inside an iq-tar file.

Optionally, an iq-tar file can contain the following file:

●

I/Q preview XSLT file, e.g. open_IqTar_xml_file_in_web_browser.xslt

Contains a stylesheet to display the I/Q parameter XML file and a preview of the

I/Q data in a web browser.

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

<?xml version="1.0" encoding="UTF-8"?>

<?xml-stylesheet type="text/xsl"

href="open_IqTar_xml_file_in_web_browser.xslt"?>

<RS_IQ_TAR_FileFormat fileFormatVersion="1"
