Patent ID: 8811461

Claim:
A method of facilitating wireless testing of a radio frequency (RF) signal transceiver device under test (DUT), comprising: receiving at least one plurality of wireless RF test signals having a plurality of respective RF test signal phases and related to a common RF test signal radiated from a DUT disposed within an interior region of a structure, wherein said common RF test signal includes a plurality of RF signal frequencies defining a RF signal frequency range, and said structure defines said interior region and an exterior region, and is configured to substantially isolate said interior region from electromagnetic radiation originating from said exterior region; controlling respective phases of at least a portion of said plurality of respective RF test signals to provide a plurality of phase-controlled RF signals; combining at least said plurality of phase-controlled RF signals to provide a composite RF signal having a signal power level at each one of said plurality of RF signal frequencies; and repeating said receiving, controlling and combining until each one of a plurality of power level differences between said signal power levels at respective pairs of a portion of said plurality of RF signal frequencies has a value between predetermined minimum and maximum values.
