System and method for testing radio frequency wireless signal transceivers using wireless test signals

An apparatus including a system to facilitate wireless testing of a radio frequency (RF) signal transceiver device under test (DUT), comprising:

• a structure defining interior and exterior regions and configured to allow placement of a DUT within said interior region and to be substantially isolated from electromagnetic radiation originating from said exterior region;
• a plurality of antennas disposed at least partially within said interior region to receive at least one plurality of wireless RF test signals related to a common RF test signal radiated from said DUT;
• and
• RF signal control circuitry coupled to said plurality of antennas and responsive to said at least one plurality of wireless RF test signals by
• controlling, in accordance with one or more phase control signals, respective phases of at least a portion of said at least one plurality of wireless RF test signals to provide at least one plurality of phase-controlled RF test signals, and
• measuring and combining said at least one plurality of phase-controlled RF test signals to provide said one or more phase control signals and a RF output signal related to a combination of said at least one plurality of phase-controlled RF test signals.
