Abstract

A measurement method for increasing the effective size of a quiet zone is provided. The measurement method comprises the step of in the case that an amplitude and/or a phase distribution of the quiet zone is known, determining a set of correction factors on the basis of said amplitude and/or phase distribution of the quiet zone. Additionally or alternatively in the case that the amplitude and/or phase distribution of the quiet zone and an antenna radiating aperture location on a device under test are known, the device under test is centered in the middle of the quiet zone and the device under test is moved radially in at least one axis.
