Bibliography

This method is sometimes named mode stirred chamber, suitable for virtually any type of microwave component and having no theoretical upper limit. It is only limited toward low frequencies by the size of the test equipment.

Describes the measurement of screening attenuation by the reverberation, or stirred, chamber, suitable for virtually any type of microwave component and having no theoretical upper frequency limit. It is only limited toward low frequencies due to the size of the test equipment, which is frequency dependent and is only one of several methods of measuring sreening attenuation. For the purpose of this standard, examples of microwave components are waveguides, phase shifters, diplexers/multiplexers, power dividers/combiners, etc.
