Abstract
Systems and methods for testing a wireless device having a beamforming circuit are disclosed herein. An exemplary system includes a shielded test enclosure, a wireless channel emulator, and a test instrument. The shielded test enclosure provides a cable-free connection between the wireless device and the wireless channel emulator, thereby allowing for testing of various types of wireless devices, particularly those that do not have radio-frequency (RF) connectors. The shielded test enclosure is smaller in size and less-expensive than traditional multi-probe anechoic chambers. In one example application, the shielded test enclosure is used to house a multiple-input multiple-output (MIMO) antenna array of a wireless device and a probe antenna array. The probe antenna array is coupled to the wireless channel emulator and used to receive signals from MIMO antenna arrays of various sizes thereby eliminating the need to uniquely tailor the probe antenna array to any specific MIMO antenna array.
