GB/T19954.1-2005

电磁兼容专业用途的音频、视频、

音视频和娱乐场所灯光控制设备的

产品类标准第1部分:发射

范围

GB/T19954的本部分适用于在第4章描述的电磁环境中使用的和在第3章定义的专业音频、视

频、音视频设备及娱乐灯光控制设备，包括3.5定义的数字设备和6.3中定义的部件。

覆盖的骚扰信号频率范围为。Hz-400GHz，但并未对整个频段做出要求

注1:附录D提供了波长0.7r-1.61-的红外发射装置的有关资料

不考虑骚扰源或受干扰设备的故障条件。

3.4,3.5和3.6中定义的设备可能运行在任何电源形式下

注2:这些供电电源的实例包括:

.公共低压电网;

·具有类似特征的独立电网;

.特定用于设备的直流源

·设备内置的电池;

·备用发电机

注3:特殊情况下，例如设备与高敏感性设备临近使用，应对其进行额外的测量来限制电磁发射，使其低于规定值

电平。

注4专业用户接收设备可能对骚扰非常敏感，有关信息见附录E。

本部分不适用于:

·消费类电子产品;

·特定设计的安保系统设备;

·设计用于无线通信的发射设备

本部分规定了适用范围中所述设备的限值和测量方法，涉及连续和暂态骚扰、传导和辐射骚扰。

这些要求代表了必要的电磁兼容性要求。

2规范性引用文件

下列文件中的条款通过GB/T19954的本部分的引用而成为本部分的条款。凡是注日期的引用文

件，其随后所有的修改单(不包括勘误的内容)或修订版均不适用于本部分，然而，鼓励根据本部分达成

协议的各方研究是否可使用这些文件的最新版本。凡是不注日期的引用文件，其最新版本适用于本

部分。
