摘要：

高速光传输引入矢量调制格式对信号质量测量和性能分析提出了新的挑战和需求。误差矢量幅度（EVM）是测试评估矢量调制信号的重要参数，在分析EVM参数定义、测试方法和设备的基础上，讨论EVM及其相关参数测量的应用现状和标准化进展。

关键词: 误差矢量幅度, 光信噪比, 质量因子, 误码率

Abstract:

Vector modulation format of high speed optical communication system calls for new measurement and analysis scheme.Error vector magnitude (EVM) is one of the most important parameters in vector modulation evaluation.The definition of EVM parameters,its test methods and instruments were analyzed,and application of EVM related parameter in transmitter measurement and its standardization progress were also discussed.

Key words: EVM, OSNR, Q factor, BER
