Cable assemblies, cables, connectors and passive microwave components - Screening attenuation measurement by the reverberation chamber method
IEC 61726:2022 describes the measurement of screening attenuation by the reverberation chamber measurement method, also called mode stirred chamber method.This document is applicable to screening attenuation measurements of cable assemblies, cables, connectors, and passive microwave components, such as waveguides, phase shifters, diplexers/multiplexers, power dividers/combiners, etc.This fourth edition cancels and replaces the third edition published in 2015. This edition includes the following significant technical changes with respect to the previous edition:a. reworded Clause 1 "Scope";b. replaced IEC TS 62153-4-1 by IEC 62153 (all parts) in Clause 2;c. added the definition of screening attenuation in 3.1;d. added Clause 4 "Principle of screening attenuation measurement";e. added the descriptions of some test set-ups, such as frequency synthesizer, spectrum analyser, stepper motor, linking devices and the sampling system, etc. in Clause 5;f. added Clause 6 "DUT";g. reworded Clause 7 "Measurement procedure";h. added Clause 8 "Caution notes";i. added Clause 9 "Acceptance criterion";j. added Clause 10 "Information to be given in the relevant specification".

Cable assemblies, cables, connectors and passive microwave components - Screening attenuation measurement by the reverberation chamber method
IEC 61726:2015 describes the measurement of screening attenuation by the reverberation chamber test method, sometimes named mode 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 screening attenuation. For the purpose of this standard, examples of microwave components are waveguides, phase shifters, diplexers/multiplexers, power dividers/combiners etc. This third edition cancels and replaces the second edition, published in 1999. This edition constitutes a technical revision. It takes into account the latest developments in the design of reverberation chambers as described in IEC 61000-4-21, which is also referencing this standard as a possible test method. Furthermore, an alternative measurement procedure is added which is able to reduce the measurement time needed.
