Defines the measurement of screening attenuation, by the reverberation chamber test method, otherwise known as mode stirred chamber. It is suited to virtually any type of microwave component and with no theoretical upper frequency limit. It is limited only toward low frequencies, due to the size of the test equipment, which is dependent upon frequency and is one of several methods of measuring screen attenuation. Examples of microwave components would be waveguides, phase shifters, multiplexers/diplexers, power dividers/combiners etc.
