Abstract

A method for measuring performance of at least one DUT in a reverberation chamber over a frequency band, the method including, iteratively: generating a fading scenario by the reverberation chamber; identifying at least one measurement sub-band included in the frequency band, wherein the at least one measurement sub-band complies with a gain flatness criterion; measuring performance of the at least one DUT in the at least one identified measurement sub-band, thereby generating at least one performance measurement result; accumulating the at least one performance measurement result; and determining measurement coverage and terminating the performance measurement in case the measurement coverage meets a coverage criterion.
