Abstract
An apparatus including a chamber that 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. At least one moveable object and chamber antenna are arranged in the cavity. A measuring instrument is connected to the device under test and the chamber antenna, for measuring the transmission between them. Further, an improved antenna holder is disclosed, comprising three surfaces of a reflective material, said surfaces extending in planes which are orthogonal in relation to each other and each surface facing away from the other surfaces, and wherein a chamber antenna is arranged on each of said at least three surfaces. Other improvements relate to video surveillance, channel emulation and shielding.
