tion marks.
1.3.2 Conventions for Procedure Descriptions
When operating the instrument, several alternative methods may be available to perform 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 additionally 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 procedures.
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 keyboard.
1.3.3 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 installed. Thus, some functions shown in the screenshots may not be available in your particular product configuration.

Welcome to the R&S SMW-K551 Option
Accessing the Slow IQ Settings
The R&S SMW-K551 is a software option that allows you to generate digital signals
with reduced speed. These kind of signals are commonly known as "Slow IQ" signals.
R&S SMW-K551 key features
●
Generation of single stream or multiplexed digital signals with potentially reduced
speed (a.k.a. "Slow IQ")
●
Generation of digital signals with data rate as required by the DUT and as requested by the processing instrument, e.g. R&S EX-IQ-Box
●
Simultaneous output of up to eight digital streams on two digital interfaces
This user manual contains a description of the functionality that the application provides, including remote control operation.
All functions not discussed in this manual are the same as in the base unit and are
described in the R&S SMW user manual. The latest version is available at:
www.rohde-schwarz.com/manual/SMW200A
Installation
You can find detailed installation instructions in the delivery of the option or in the
R&S SMW service manual.
2.1 Accessing the Slow IQ Settings
To open the dialog with the required settings
1. In the task bar R&S SMW, select the "System Configuration > System Configura-
tion".
A dialog box opens that displays the "Fading/Baseband Configuration" settings.
2. Select "Signal Outputs > Digital Only/Digital Only Multiplexed".
3. Select "Ok".
The signal generation is not started immediately. To start signal generation with the
default settings, select "State > On".
