Abstract

A measurement method of performing over-the-air (OTA) measurements on a device under test (12) is described. The measurement method comprises the steps of- providing a measurement antenna array (14), wherein the measurement antenna array (14) comprises a plurality of measurement antennas (40) having an adjustable signal weight to a measurement signal processed by the measurement antenna array (14), respectively;- selecting, by means of a control circuit (22), a measurement antenna subset (38), wherein the measurement antenna subset (38) comprises at least one of the plurality of measurement antennas (40);- receiving, by means of the selected measurement antenna subset (38), electromagnetic waves generated by at least one antenna (34, 36) to be tested, thereby obtaining the measurement signal that is forwarded to a processing circuit (24);- receiving, by means of the processing circuit (24), a reference signal from a reference signal source; and- determining, by means of the processing circuit (24), at least one measurement parameter associated with the at least one antenna (34, 36) to be tested based on the measurement signal and based on the reference signal.Further, a measurement system (10) for performing OTA measurements on a device under test (12) is described.
