1. A system used to test a cell phone that uses multiple cell phone antennas, including:

  • at least one signal feed adapted to be coupled to the cell phone at a location that bypasses the cell phone antennas;

    at least one memory; and

    one or more channel generator modules running on one or more processors, coupled to the signal feed and the memory, wherein each channel generator moduleuses at least three correlation data sets stored in the memory to emulate different channel conditions of a propagation channel model (abbreviated “

    PCM”

    ), the different channel conditions representing time-varying physical relationships between multiple base station antennas and the multiple cell phone antennas; and

    conditions a test signal with the different channel conditions and passes the conditioned test signal to the signal feed; and

    a measurement module running on one or more of the processors, coupled to the signal feed, that measures response of the cell phone to the conditioned test signal.
