BS EN 50561-3:2016规定了无线电干扰特性的限值和测量方法 使用低压电源装置作为传输介质的家用通信设备。 EN 50561的本部分适用于使用频率（包括30 MHz以上频率）的设备，以便 交流给出了测量设备产生的信号的程序，并规定了限值 在9 kHz到400 GHz的频率范围内。在没有限制的频率下无需测量 都是指定的。本标准中的辐射发射要求不适用于有意 来自ITU定义的无线电发射机的传输，以及与之相关的任何虚假发射 故意传输。注:本标准中定义的要求有效地将预期传输频率限制在87.5 MHz以下。交叉引用:EN 50561-1:2013EN 55032:2012EN 55016-1-1:2010EN 55016-1-2:2004EN 55016-4-2:2011EN 55016-1-4:2010购买本文件时可获得的所有现行修订均包含在购买本文件中。

BS EN 50561-3:2016 specifies limits and methods of measurement of radio disturbance characteristics for in-home communication apparatus that use the low voltage power installation as the transmission medium. This part of EN 50561 applies to equipment that uses frequencies including those above 30 MHz in order to communicate.Procedures are given for the measurement of signals generated by the equipment and limits are specified within the frequency range 9 kHz to 400 GHz. No measurement is required at frequencies where no limits are specified.The radiated emission requirements in this standard are not intended to be applicable to the intentional transmissions from a radio-transmitter as defined by the ITU, nor to any spurious emissions related to these intentional transmissions.NOTE The requirements defined in this standard effectively restrict the intended transmission frequencies to below 87,5 MHz.Cross References:EN 50561-1:2013EN 55032:2012EN 55016-1-1:2010EN 55016-1-2:2004EN 55016-4-2:2011EN 55016-1-4:2010All current amendments available at time of purchase are included with the purchase of this document.
