Switched MIMO

Half Duplex RF Input

In the case of 3x3 switched MIMO, one of the half-duplex ports (RF3 I|O or RF4
I|O) must be designated as an RF input port for the third input. In the
Input/Output > Input > Half Duplex Input Port menu, select RFIO3 or RFIO4,
so that the RF3 I|O port or the RF4 I|O port is defined as the input port.
The equivalent menu path for the Traditional interface is:
Input/Output > RF Output & Test Set Config > Half Duplex Config > RF Input
Port
The equivalent SCPI command is:
[:SENSe]:HDUPlex:PORT:INPut RFIO3|RFIO4

Acquisition Triggers

Each of the acquisitions which make up a sequence used for switched MIMO
testing needs to have the same trigger settings as the others.

Acquisition Integration

For 2x2 switched MIMO in Sequence Analyzer mode, two separate acquisitions
are used for the two separate ports, and must be integrated. Set up acquisition
integration as follows: in the Meas Setup > Settings > Integration Type menu,
select Primary for the first acquisition and Switch MIMO for the second. The
equivalent SCPI commands are:
[:SENSe]:LSEQuencer:ACQuire{1:512}:SETup:INTegration PRIMary
[:SENSe]:LSEQuencer:ACQuire{1:512}:SETup:INTegration SMIMo
The equivalent menu path for the Traditional interface is:
Meas Setup > Acquisition Setup > Acquisition Integration
For 3x3 switched MIMO in Sequence Analyzer mode, three separate
acquisitions are used for the three separate ports, and must be integrated. Set
up acquisition integration as follows: in the Meas Setup > Settings >
Integration Type menu, select Primary for the first acquisition and Switch
MIMO for the second and third. The equivalent SCPI commands are:
[:SENSe]:LSEQuencer:ACQuire{1:512}:SETup:INTegration PRIMary
[:SENSe]:LSEQuencer:ACQuire{1:512}:SETup:INTegration SMIMo
[:SENSe]:LSEQuencer:ACQuire{1:512}:SETup:INTegration SMIMo
The equivalent menu path for the Traditional interface is:
Meas Setup > Acquisition Setup > Acquisition Integration

The integration parameter can also be set within the complex
command which is used to set the Acquisition RF Input Port (see
"Acquisition RF Input Port" on page 117
parameter is the one which comes immediately before the Acquisition
RF Input Port parameter.
