Introduction to the use of Composite MIMO]

Composite MIMO is one of the three current mainstream WLAN MIMO test solutions.

Composite MIMO can double the efficiency of multi-channel wireless testing under the condition of limited instrument resources. Composite MIMO only supports VSA test, that is, only supports TX test of DUT, which is suitable for production scenarios of DUT products. Because Composite MIMO mixes multi-stream signals through a power splitter, so

The Composite MIMO test must have a reference file to distinguish multiple streams during analysis, and the reference file must match the signal type of the DUT test.

[Test networking mode]

The multiple antennas of the DUT are mixed through the power splitter and then connected to one RF port of the instrument. The connection between the DUT and the instrument can only connect to one RF port
