| 摘 要： | 在公式推导和理论计算的基础上,对发射测量＂6 dB原则＂进行了解析,并由此引申出对EUT电平、环境电平与标准限值之间的关系探讨和测量偏差分析,认为电磁环境电平与来自EUT的发射电平之差的大小会显著影响EUT测量结果的有效性。

| Abstract: | Based on formula deduction and mathematical calculation,the 6 dB Principle used in emission test is analyzed.The relationship among EUT output level,ambient noise level,and limits in standard is discussed,and analysis of measuring deviation is proposed as well.So that it demonstrates the difference between EM environment and the emission from EUT could impact the validity of emission test result. |
