3. In the "External Instrument Configuration" dialog, select "Show Connector".
A blinking LED on the rear of the instrument indicates the connector's position.
Tip: Cross-check whether this digital interface is defined as input or output, before
you connect the external instrument.
To find out the connector's direction
The directions of the digital interfaces at the FADER boards are configurable parame-
ter. Depending on the test setup, each of these connectors can serve as an input or an
output connector but not at the same time.
To find out the currently selected connector's direction and the currently defined con-
nectors, proceed as follows:
1. Select "Taskbar > System Configuration > External RF and I/Q".
2. In the overview table, navigate to the required connector.
Observe the value of the parameter "Direction".
3.9.3 How to Define the MIMO Scenario

To simulate complex MxN MIMO scenarios using the "Fading and Baseband
Configuration" settings
The configuration of complex MIMO scenarios undergoes the same steps. We use the
configuration of a 1x4x4 MIMO scenario with coupled sources as example to explain
the principle.

tion", on page 192.
