Abstract
A system and method for facilitating wireless testing of a radio frequency (RF) signal transceiver device under test (DUT). Using multiple antennas within a shielded enclosure containing the DUT, multiple wireless RF test signals resulting from a RF test signal radiated from the DUT can be captured and have their respective signal phases controlled in accordance with one or more signal characteristics, including their respective signal power levels, their respective signal phases as received, and a signal power level of a combination of the received signals. Such phase control of the captured wireless RF test signals can be performed individually for any DUT tested within the shielded enclosure, thereby providing compensation for the multipath signal environment within the shielded enclosure irrespective of the placement of the DUT, and thereby simulating a wired test signal path during wireless testing of the DUT.
