Abstract
A 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 are captured and their respective signal phases are controlled prior to being combined to form a composite RF signal. This process is repeated until power level differences between signal power levels at respective pairs of a selected number of RF signal frequencies have values between predetermined minimum and maximum values, thereby providing compensation for the multipath signal environment within the shielded enclosure, and thereby simulating a wired test signal path during wireless testing of the DUT.
