The graphic depicts the main phases for connecting and configuring the R&S SMW
and the external instruments. This illustration is a simplified diagram that highlights the
configuration stages performed in the "System Configuration" dialog.
For relevant information on the configuration of the baseband source signal or using
the fading simulator and the AWGN generator, see:

4.9.1 Finding Out the Suitable Configuration for Your Test Situation
For conceptual information on the workflow, refer to "General workflow for finding out
the suitable system configuration for a current use case" on page 107.
1. Select a system configuration form the test cases listed in Table 4-1.
The table provides a cross-reference between a test scenario and the required
configuration.
2. Select "Taskbar > System Configuration > Fading/Baseband Settings":
● Follow the instructions in "To simulate complex MxN MIMO scenarios using the
"Fading and Baseband Configuration" settings" on page 191.
