标准摘要
[中文适用范围]： 本部分ISO/IEC 11801涉及由标称阻抗为100 Ω的组件构建的通道描述。 a) 类别I：基于即将推出的类别8.1组件的30米通道。该通道与ISO/IEC 11801相比，与类别EA通道相比提供了更大的余量，并且最高频率限制为1600 MHz（2000 MHz ffs）。 b) 类别II：基于即将推出的类别8.2组件的30米通道。该通道与ISO/IEC 11801相比，与类别FA通道相比提供了更大的余量，并且最高频率限制为1600 MHz（2000 MHz ffs）。 c) 基于ISO/IEC 11801类别6A组件构建的通道，长度校正到30米。 d) 基于ISO/IEC 11801类别7A组件构建的通道，长度校正到30米。 e) 基于ISO/IEC 11801类别6A组件构建的通道，长度校正到30米，并在当前最高频率以上进行表征（见附录B）。 f) 基于ISO/IEC 11801类别7A组件构建的通道，长度校正到30米，并在当前最高频率以上进行表征（见附录B）。 [外文原描述]： ISO/IEC TR 11801:2014(E) covers the following channel descriptions constructed from components with a nominal impedance of 100: - Class I: 30 m channel based on upcoming Category 8.1 components. This channel provides increased margin compared to ISO/IEC 11801, Class EA channels, and an upper frequency limit of 1 600 MHz (2 000 MHz (ffs); - Class II: 30 m channel based on upcoming Category 8.2 components. This channel provides increased margin compared to ISO/IEC 11801, Class FA channels, and an upper frequency limit of 1 600 MHz (2 000 MHz ffs); - Channels based on Category 6A components of ISO/IEC 11801, length corrected to 30 m; - Channels based on Category 7A components of ISO/IEC 11801, length corrected to 30 m; - Channels based on Category 6A components of ISO/IEC 11801, length corrected to 30 m, characterized beyond the current upper frequency; - Channels based on Category 7A components of ISO/IEC 11801, length corrected to 30 m, characterized beyond the current upper frequency.
