Abstract
A test system for testing a DUT includes near field and intermediate field measurement devices located in a near field and an intermediate field, respectively, of the DUT antenna that sample first and second bounded radiation surfaces, respectively, comprising RF signals emitted by the DUT antenna in at least first and second directions in which the bounded radiation surfaces extend. A receiver of the test system generates first and second matrices of near field and intermediate field values, respectively, from the samples obtained by the near field and intermediate field measurement devices, respectively and inputs them to processing logic of the test system. The processing logic processes the first and second matrices of near field and intermediate field values, respectively, and derives a third matrix of near field phase values therefrom.
