Tip: To route more streams to one output connector, in the"I/Q Stream Mapper"
dialog and for the particular connector, select "Combination> Add" and select the
streams to be routed to it.
3.9.5 How to Cable the Instruments in MIMO Test Setups
The MxN MIMO test setups with more than two Rx antennas (N>2) require the signal
of at least three antennas. The R&S SMW generates the required signal and outputs
two of the antennas signals at the RF outputs. The others signals can be routed to the
provided analog and digital I/Q connectors and then processed by a connected instru-
ment, like an RF frontend. Several RF frontend instruments can serve as extended
RFs for the R&S SMW, for example R&S SGS, R&S SGT, or R&S SMBV.
The Figure 3-17 shows a 1x4x4 MIMO test setup with two R&S SGS connected to the
analog I/Q outputs of the R&S SMW.
For information on how to connect instruments to the HS DIG I/Q interfaces, see Fig-
ure 3-19.
