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

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.

Description

technical field [0001] This patent application is a continuation in part of U.S. Patent Application 13 / 839,162 filed on March 15, 2013 and entitled "System and Method for Testing Radio Frequency Wireless Signal Transceivers Using Wireless Test Signals" (System and Method for Testing Radio Frequency Wireless Signal Transceivers Using Wireless Test Signals), and 2013 Continuation-in-Part of U.S. Patent Application 13 / 839,583, filed March 15 and entitled "System and Method for Testing Radio Frequency Wireless Signal Transceivers Using Wireless Test Signals," the contents of which are incorporated by reference into this article. Background technique [0002] The present invention relates to testing radio frequency (RF) wireless signal transceivers, and more particularly to testing such devices without the use of RF signal cables that transmit RF test signals. [0003] Many of today's electronic devices use wireless technology for both connection and communication purposes. Bec...
