Abstract
A system for testing a device under test, DUT, comprises a holder configured to hold the DUT, wherein the DUT comprises at least one reconfigurable intelligent surface, RIS. A first antenna array generates plane waves at a position of the at least one RIS when the DUT is arranged on the holder. The first antenna array can generate plane waves having different angles of incidence at the position of the at least one RIS. A second antenna array receives a reflection signal originating from a reflection of a plane wave, wherein the plane wave is generated by the first antenna array and is reflected from the at least one RIS. A determination unit determines an angle of incidence on the second antenna array, using the received reflection signal.
