1 Preface
This chapter provides safety-related information, an overview of the user documenta-
tion and the conventions used in the documentation.
1.1 About this Manual
This User Manual describes general instrument functions and settings common to all
applications and operating modes in the R&S FSW. Furthermore, it provides all the
information specific to RF measurements in the Spectrum application. All other
operating modes and applications are described in the specific application manuals.
The main focus in this manual is on the measurement results and the tasks required to
obtain them. The following topics are included:
●Welcome to the R&S FSW
Introduction to and getting familiar with the instrument
●Operating Modes and Applications
The concept of using multiple operating modes
●Measurements
Descriptions of the individual measurements in the Spectrum application, including
result types and configuration settings.
●Common Measurement Settings
Description of the measurement settings common to all measurement types with
their corresponding remote control commands
●Common Measurement Analysis and Display Functions
Description of the settings and functions provided to analyze results independently
of the measurement type with their corresponding remote control commands
●Data Management
Description of general functions to handle data files (configuration and result data,
not I/Q data)
●General Instrument Setup
Description of general instrument settings and functions that are independent of
the current operating mode
●Network and Remote Operation
Information on setting up the instrument in a network and operating it remotely.
●Remote Commands
Remote commands required to configure and perform measurements in a remote
environment, sorted by tasks
Remote commands required to set up the environment and to perform common
tasks on the instrument, sorted by tasks
Programming examples demonstrate the use of many commands and can usually
be executed directly for test purposes
●Maintenance
Information on tasks required to maintain operability of the instrument

1.2 Conventions Used in the Documentation
1.2.1 Typographical Conventions
The following text markers are used throughout this documentation:
Convention Description
"Graphical user interface ele-
ments"
All names of graphical user interface elements on the screen, such as
dialog boxes, menus, options, buttons, and softkeys are enclosed by
quotation marks.
[Keys] Key and knob names are enclosed by square brackets.
Filenames, commands,
program code
Filenames, commands, coding samples and screen output are distin-
guished by their font.
Input Input to be entered by the user is displayed in italics.
Links Links that you can click are displayed in blue font.
"References" References to other parts of the documentation are enclosed by quota-
tion marks.
1.2.2 Conventions for Procedure Descriptions
When operating the instrument, several alternative methods may be available to per-
form the same task. In this case, the procedure using the touchscreen is described.
Any elements that can be activated by touching can also be clicked using an addition-
ally connected mouse. The alternative procedure using the keys on the instrument or
the on-screen keyboard is only described if it deviates from the standard operating pro-
cedures.
The term "select" may refer to any of the described methods, i.e. using a finger on the
touchscreen, a mouse pointer in the display, or a key on the instrument or on a key-
board.
1.2.3 Notes on Screenshots
When describing the functions of the product, we use sample screenshots. These
screenshots are meant to illustrate as many 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.

2 Safety Information
The product documentation helps you use the R&S FSW safely and efficiently. Follow
the instructions provided here and in the printed "Basic Safety Instructions". Keep the
product documentation nearby and offer it to other users.
Intended use
The R&S FSW is intended for the development, production and verification of elec-
tronic components and devices in industrial, administrative, and laboratory environ-
ments. Use the R&S FSW only for its designated purpose. Observe the operating con-
ditions and performance limits stated in the data sheet.
Where do I find safety information?
Safety information is part of the product documentation. It warns you about the poten-
tial dangers and gives instructions how to prevent personal injuries or damage caused
by dangerous situations. Safety information is provided as follows:
●The printed "Basic Safety Instructions" provide safety information in many lan-
guages and are delivered with the R&S FSW.
●Throughout the documentation, safety instructions are provided when you need to
take care during setup or operation.
