1 Preface
1.1 About this Manual
This user manual provides all the information specific to the GNSS options. All gen-
eral instrument functions and settings common to all applications and operating modes
are described in the main R&S SMW user manual.
The main focus in this manual is on the provided settings and the tasks required to
generate a signal. The following topics are included:
●Introduction to and getting familiar with the options
●About the GNSS options
Background information on basic terms and principles in the context of the signal
generation
●GNSS Configuration and Settings
A concise description of all functions and settings available to configure signal gen-
eration with their corresponding remote control command
●How to Perform Typical Signal Generation Tasks with the GNSS Options
The basic procedure to perform signal generation tasks and step-by-step instruc-
tions for more complex tasks or alternative methods
As well as detailed examples to guide you through typical signal generation sce-
narios and allow you to try out the application immediately
●Remote Control Commands
Remote commands required to configure and perform signal generation in a
remote environment, sorted by tasks
(Commands required to set up the instrument or to perform common tasks on the
instrument are provided in the main R&S SMW user manual)
Programming examples demonstrate the use of many commands and can usually
be executed directly for test purposes
●Annex
Reference material such as description of file formats, extensive lists, and tables
●List of remote commands
Alphabetical list of all remote commands described in the manual
●Index
Contents and scope
This description assumes R&S SMW equipped with all availabe options. Depending on
your model and the installed options, some of the functions may not be available on
your instrument.
Notes on screenshots
When describing the functions of the product, we use sample screenshots. These
screenshots are meant to illustrate as much as possible of the provided functions and

possible interdependencies between parameters. The shown values may not represent
realistic usage scenarios.
The screenshots usually show a fully equipped product, that is: with all options instal-
led. Thus, some functions shown in the screenshots may not be available in your par-
ticular product configuration.
1.2 Documentation Overview
This section provides an overview of the R&S SMW user documentation. Unless speci-
fied otherwise, you find the documents on the R&S SMW product page at:
www.rohde-schwarz.com/manual/smw200a
1.2.1 Getting Started Manual
Introduces the R&S SMW and describes how to set up and start working with the prod-
uct. Includes basic operations, typical measurement examples, and general informa-
tion, e.g. safety instructions, etc. A printed version is delivered with the instrument.
1.2.2 User Manuals and Help
Separate manuals for the base unit and the software options are provided for down-
load:
●Base unit manual
Contains the description of all instrument modes and functions. It also provides an
introduction to remote control, a complete description of the remote control com-
mands with programming examples, and information on maintenance, instrument
interfaces and error messages. Includes the contents of the getting started manual.
●Software option manual
Contains the description of the specific functions of an option. Basic information on
operating the R&S SMW is not included.
The contents of the user manuals are available as help in the R&S SMW. The help
offers quick, context-sensitive access to the complete information for the base unit and
the software options.
All user manuals are also available for download or for immediate display on the Inter-
net.
1.2.3 Tutorials
The R&S SMW provides interactive examples and demonstrations on operating the
instrument in form of tutorials. A set of tutorials is available directly on the instrument.
