3.9.1 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 123.
1. Select a system configuration form the test cases listed in Table 3-1.
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 193.
● Observe the preview diagram in the "Fading/Baseband Settings" dialog.
This diagram provides a short description and an example of the common applica-
tion or test scenario of the selected configuration.
For description of the further steps, see:
● Chapter 3.9.3, "How to Define the MIMO Scenario", on page 193
● Chapter 3.9.4, "How to Route the I/Q Streams to the Output Interfaces",
on page 196

3.9.2 How to Find Out where the Input/Output Interface Is Located
See:
●
"To find out the correct connector" on page 192
●
"To find out the connector's direction" on page 193
To find out the correct connector
1. Select "Taskbar > System Configuration > External RF and I/Q".
2. In the overview table, navigate to the connector an external instrument has to be
connected to (e.g. "BBMM 1").
Select "External Instruments > Config".
