Abstract

See full text

A measurement system for testing a device under test includes a signal generation and/or analysis equipment, several antennas, several reflectors and a test location for the device under test. The antennas are connected with the signal generation and/or analysis equipment in a signal-transmitting manner Each of the antennas is configured to transmit and/or receive an electromagnetic signal so that a beam path is provided between the respective antenna and the test location. The electromagnetic signal is reflected by the respective reflector so that the electromagnetic signal corresponds to a planar wave. Each antenna and the corresponding reflector together are configured to provide a corresponding quiet zone at the test location. At least one of the quiet zones provided is larger than the at least one other quiet zone and/or at least one of the antennas is configured to operate at a different frequency compared to the at least one other antenna. Further, a method of performing an over-the-air test of a device under test is described.
