Modulation System Sirius Digital Radio
2 Introduction
The R&S Signal Generator enables you to generate signals in accordance with the Sirius satellite radio standard.
The equipment layout of the instrument for generating multicarrier signals includes:
●
Option Baseband Main Module (R&S SMx/AMU-B13)
●
Options Baseband Generator (R&S SMx/AMU-B9/B10/B11)
Options Baseband Generator (R&S SMx/AMU-B10/B51)
(per signal path)
●
Sirius Digital Radio (R&S SMx/AMU-K58)
(per signal path)
Per baseband, one satellite signal or one terrestrial signal can be generated.
2.1 Modulation System Sirius Digital Radio
The Sirus Radio signal is transmitted via two satellites (QPSK-modulation) and additionally via one terrestrial repeater (COFDM-modulation).
Figure 2-1: Sirius frequency band
The following table shows the carrier frequencies for the corresponding channels:

IntroductionSirius Radio
Handling of Data Sources
2.2 Handling of Data Sources
2.2.1 Using Data Lists and Sirius Test Files
For the simulation of Sirius radio, the R&S Signal Generator provides two main data
sources: data lists and Sirius files.
Although any of the standard data sources can be used, the generation of signals in
accordance to the Sirius satellite radio standard requires that the files provided by Sirius satellite radio are used.
The data lists are Rohde&Schwarz proprietary files with extension *.dm_iqd, that can
be created and modified in the data list editor (see "Data List Management"
on page 14).
The official Sirius test files are provided by Sirius satellite radio. There are two types of
test files currently available in the field: encrypted Sirius test files and the still in use
non-encrypted files. R&S Signal Generator supports both of them.
The non-encrypted test files are the former Sirius test files; they are files with extension
*.tdm and are not provided any more by Sirius satellite radio.
The currently provides test files are encrypted to ensure the usage of the appropriate
files. The encrypted test files are delivered in form of the so called triples, containing an
encrypted test file with extension *.sirius_iqd and two support files with extensions
*.sirus_subkey1 and *.sirius_subkey2 respectively.
Each signal generator manufacturer uses it own encrypting procedure.Files encrypted
by one signal generator manufacturer cannot be decrypted by or used with the signal
generators of other manufactures.
There are no Sirius test files installed on the R&S Signal Generator and
Rohde&Schwarz does not provide any Sirius test files. Requesting of encrypted Sirius
test files by Sirius satellite radio is under the responsibility of the customer.
The encrypted triples of Sirius test files and the non-encrypted test files have to be
stored on the hard disk or on a USB flash drive connected to the R&S Signal Generator. The filenames and the directory they are stored in are user-definable. The files
belonging to a triple must be stored in the same directory (see an example on the figure below).
Sirius test files can be for instance downloaded via the internet. They are available at
the following page: www.arena.com

IntroductionSirius Radio
Handling of Data Sources
2.2.2 Test Files Handling in the R&S Signal Generator
To play a Sirius test file with the R&S Signal Generator, the corresponding file has to
be selected as a data source for the signal generation. Set the Data Source to "Data
List" and select the required file in theSelect Data List dialog.
The encrypted Sirius test files are decrypted by the R&S Signal Generator in real time
and the decrypted files are not stored on the hard drive of the instrument. Each encrypted file has a timestamp; the expiration date of the test file is displayed on the user
interface (see "Expire Date" on page 15). The test files are rendered unusable after
the expiration date and as long no new license is available. The R&S Signal Generator
informs you with a warning message if the encrypted files are about to expire.

The dialog for setting the Sirius Radio digital standard is either called from the "Baseband" block or from the menu tree under "Baseband".
The screenshots provided in this description show parameter values that have been
selected to illustrate as much as possible of the provided functions and possible interdependencies between them.
These values are not necessarily representative of realistic test situations.
3.1 General Settings
The menu is split into several sections for configuring the standard.
The upper menu section is where the Sirius Radio digital standard is activated and
deactivated. Configuration settings can be stored and already stored configuration settings can be loaded.
In the next section, the physical layer, the physical layer transmission and the data
source are selected.
In the "Terrestrial Parameters" section, the parameters for the terrestrial transponder
are set.
In the "Satellite Parameters" section, the parameters for the satellite transponder are
set.
