标准范围

IEC 61726:2015（E）描述了混响室试验方法（有时称为模式搅拌室）对屏蔽衰减的测量，该方法适用于几乎任何类型的微波组件，且没有理论上的频率上限。由于测试设备的尺寸，它仅限于低频，这取决于频率，只是测量屏蔽衰减的几种方法之一。就本标准而言，微波组件的示例包括波导、移相器、双工器/多路复用器、功率分配器/组合器等。第三版取消并取代了1999年出版的第二版。本版为技术修订版。它考虑了IEC 61000-4-21中所述的混响室设计的最新发展，IEC 61000-4-21也将本标准作为一种可能的测试方法。此外，增加了一种替代测量程序，可以减少所需的测量时间。

IEC 61726:2015(E) 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.
