Abstract:
1. A method for facilitating testing of a plurality of devices under test (DUTs) having multiple input multiple output (MIMO) radio frequency (RF) signal transmission and reception capabilities with a plurality of vector signal analyzers (VSAs) and a plurality of vector signal generators (VSGs), comprising: providing a plurality of controllable signal paths for controlling conveyance of a plurality of RF signals between a plurality of DUTs, a plurality of VSAs and a plurality of VSGs; and receiving a plurality of control signals and in response thereto controlling respective ones of said plurality of controllable signal paths such that each one of a first portion of said plurality of controllable signal paths has a lower impedance to facilitate conveyance of one or more of said plurality of RF signals, and each one of a second portion of said plurality of controllable signal paths has a higher impedance to substantially prevent conveyance of another one or more of said plurality of RF signals, wherein, in accordance with said plurality of control signals, said plurality of controllable signal paths facilitate
