R&S® WinIQSIM™ was especially developed for the generation of digitally modulated signals. Complex signals can thus easily be generated.
The graphical user interface allows intuitive operation, supported by context-sensitive help. The convenient way of creating any TDMA frame configurations with the aid of a data editor, and the generation of multicarrier signals as well as of complex WCDMA signals make R&S® WinIQSIM™ suitable for a wide range of applications.
