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

摘要

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.

1. 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, andsaid 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.
