射频和同轴电缆组件 第2-8部分：用于无线电和电视接收机的电缆组件详细规范 频率范围高达3000 MHz，屏蔽等级A++，IEC 61169-47连接器

[中文适用范围]： IEC 60966-2-8:2025 RLV包含了官方的IEC国际标准及其红线版本。红线版本仅提供英文版，可让您快速、便捷地比较官方IEC标准与其前一版之间的所有变更。IEC 60966-2-8:2025是一项详细规范，适用于带有F-Quick连接器（参见IEC 61169-47）的线缆组件，并要求达到A++级四层屏蔽（参见IEC 61196-6-5）。本文件适用于广播电视接收设备的线缆组件。本版为第二版，取代并废止了2022年发布的首版。本版属于技术修订版。与前一版相比，本版包含以下重大技术变更：a) 在条目[5]中，增加了直角连接器的图纸；b) 在条目[12]中，取消了F型母连接器（IEC 61169-47未将其标准化）；c) 在条目[14]中，反射特性（回波损耗）：直角连接器和直角连接器的回波损耗值不同；d) 在条目[14]中，插入损耗：直角连接器和直角连接器的插入损耗计算因素不同；e) 在条目[14]中，环路电阻：对整条线缆的环路电阻设置为最大值1欧姆。 [外文原描述]： IEC 60966-2-8:2025 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60966-2-8:2025 is a detail specification that applies to cable assemblies with F-Quick connectors (see IEC 61169-47) and requires quad-shield screening class A++ (see IEC 61196-6-5). This document applies to the cable assemblies for radio and TV receivers. This second edition cancels and replaces the first edition published in 2022. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) in item [5], drawing expanded by right angled connectors; b) in item [12], female F-connectors cancelled (not standardized by IEC 61169-47); c) in item [14] Reflection properties (return loss): different values for straight and right-angled connectors; d) in item [14] Insertion loss: different factors for insertion loss calculation for straight and right-angled connectors; e) in item [14] Loop resistance: loop resistance was set to 1 Ω max. value for the complete length.
