标准摘要
[中文适用范围]: IEC 61282 这部分的目的是将误差矢量幅度 (EVM) 定义为量化来自发射机或光传输链路的光矢量调制(相位和可能幅度的调制)信号质量的度量。详细说明了可重复测量结果所需的注意事项。描述了与星座图分析中的误差矢量@相位误差@幅度误差@IQ偏移和时间分辨EVM等其他相关参数的关系以及EVM与Q因子之间的关系。 [外文原描述]: IEC/TR 61282-10:2013(E) defines the error vector magnitude (EVM) as a metric for quantifying the quality of an optical vector-modulated (modulation of phase and possibly magnitude) signal from a transmitter or optical transmission link. The considerations required for reproducible measurement results are detailed. The relationships with other related parameters from constellation diagram analysis like error vector, phase error, magnitude error, I-Q offset and time-resolved EVM are described, as well as the relationship between EVM and Q-factor. Key words: error vector magnitude (EVM), quality of an optical vector-modulated signal The contents of the corrigendum of April 2013 have been included in this copy.
