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.

Abstract: A measurement device for measuring performance of at least one antenna system in a first frequency band and in a second frequency band. The measurement device including an outer chamber having inwardly radio frequency reflective walls configured to enclose the antenna system, an inner chamber deployable inside the outer chamber, the inner chamber having radio frequency absorptive walls configured to enclose the antenna system, a first test antenna arrangement arranged inside the outer chamber and configured for a measurement operation in the first frequency band, and a second test antenna arrangement arranged inside the inner chamber and configured for a measurement operation in the second frequency band, thereby enabling measuring performance of the antenna system in a reflective radio frequency environment by the first test antenna arrangement and measuring performance in an essentially anechoic radio frequency environment by the second test antenna arrangement.

Abstract: A method and apparatus for production testing of a device under test (DUT) in a chamber is disclosed, the chamber defining an internal cavity therein, adapted to enclose the DUT, and including walls having inwardly facing surfaces of an electromagnetically reflective material, thereby supporting several resonant modes within the internal cavity.

Abstract: A new measurement arrangement and method for measuring the performance of a device under test, such as an antenna, a mobile phone and other wireless terminals, are disclosed. The chamber defines an internal cavity therein, adapted to enclose the device under test, and including walls of an inwardly reflective material, rendering the walls reflective to electromagnetic waves, thereby simulating a multi-path environment. Thus, the chamber is a reverberation chamber. Further, at least one first chamber antenna and at least one second chamber antenna, are arranged in the cavity, the first and second chamber antennas being configured to transmit and receive electromagnetic waves within a first predefined frequency range and within a second predefined frequency range, respectively. A measuring instrument is connected to the device under test and the chamber antennas, for measuring the transmission between them.
