To connect instruments to the I/Q digital interface
In this example, we assume a "Fading/Baseband Configuration > 1x4x4 MIMO" sce-
nario and the following stream mapping: Stream A and B are output at RF A and B;
stream C and D at the BBMM interfaces.
The test setup uses the digital I/Q outputs and requires two additional instruments, for
example 2xR&S SGT.
1. Connect two R&S SGT to the BBMM interfaces.
See Figure 3-19.

2. Follow the steps described in "To connect instruments to the I/Q analog interface"
on page 199.
a) In the "System Config > System Configuration > External RF und I/Q", enable
"Auto Connect > On".
b) Use the predefined initialization file initialize_SGT
The "System Configuration > External RF and I/Q" dialog confirms a correct and
successful configuration by the active "Rem Conn" status and active "I/Q Conn"
status indication.
