Abstract
The technology disclosed relates to systems and methods for testing adaptive antennas via a multi-probe anechoic chamber, which includes the emulation of real world conditions of a radio frequency (RF) signal reaching a device-under-test (DUT). The technology disclosed can be applied to test and evaluate a range of changed conditions. In one case, beamforming scenarios use separate spatial desired and interference signals, and the results can be compared to uniform interference. Based on performance for a segment of a test profile, the segment can be modified or expanded: shortened, repeated, or repeated with a modification—to fully evaluate the aspect being tested. Also, a dynamic profile that is utilized to evaluate a first device can be saved and repeated as a fixed profile for further testing of a first or second device.
