2 Signal Generation Software R&S WinIQSIM2
R&S WinIQSIM2 permits calculation of I and Q baseband signals on a Windows PC
system. It combines the advantages and functionalities of the well known previous version
of R&S WinIQSIM with the firmware of the R&S SMU/SMATE vector signal generator
family.
Among R&S WinIQSIM2’ functions are single-carrier modulation, the generation of multi
carrier, W-CDMA and other 3rd Generation signals. Future digital standards will be supported
as well.
The look-and-feel of R&S WinIQSIM2, especially the block diagram, is based on the R&S
SMU firmware. So users of R&S SMU vector signal generators can easily get used to the
handling and behavior of this software. Other users will find an easy approach as well,
since the software offers a high grade of self-explanation by means of a logically structured
signal flow diagram and menus.
The whole process of signal configuration can be controlled via the block diagram. The
current status of signal configuration and active interfering components can be seen at
a glance.
Comprehensive graphic display modes in the time and frequency domain, e.g., I(t) and
q(t), vector diagram or spectrum, allow simulation and analysis of characteristics as early
as in the design phase of new digital communications systems.
All in all, R&S WinIQSIM2 is an indispensable application for anyone engaged in stateof-the-art
digital modulation.

Control of vector signal generators
The following vector signal generators can be used for generation of radio frequency (RF)
signals. Moreover, these vector signal generators can be controlled by the R&S WinIQ-
