误差矢量

Error Vector Magnitude (EVM) is a one of many key figures of merit measuring noise, interfering signals, and nonlinear distortion.

误差矢量幅度（EVM）是测量噪声、干扰信号和非线性失真等众多关键的品质因数之一。

In Figure 10, depicted is a flow chart diagram illustrating a method 1000 for operating an example DCM error vector magnitude probe type-three (DPT-3), where the DPT-3 can be transmitted by the LMO node to the RX node on the primary channel or on the secondary channel. Not depicted by the method 1000, the DPT-3 can be transmitted by the LMO node on the primary channel, or on the secondary channel. The transmission power for DPT-3 is set according to a DCM configuration with no interferer accounted for. Also, in the optimal performance mode all the other DCM nodes (e.g., idle nodes) set their respective AFEs to transmission gain associated with the receiving node whether transmitting or not. In the low power consumption mode, all the other DCM nodes deactivate their respective AFEs. Further, the number of DPT-3 transmitted per LMO, where N is the number of DCM capable nodes in the network, is (N-1) x 2.

图10显示了示例DCM误差向量幅度第三探测类型（DPT-3）的示例操作方法1000的流程图，其中，DPT-3可由LMO节点在主要通道或辅助通道上传输给RX节点。方法1000中未显示的是，DPT-3可由主要通道或辅助通道上的LMO节点进行传输。DPT-3的传输功率根据不存在干扰信号的DCM配置而设置。另外，在最佳性能模式下，无论传输与否，所有其他DCM节点（例如，空闲节点）将其各个AFE设置为与接收节点关联的传输增益。在低功耗模式下，所有其他DCM节点停用其各个AFE。进一步，N为网络中DCM功能节点的数量时，每个LMO传输的DPT-3的数量为（N-1） x 2。

Performing common measurements, such as error vector magnitude (EVM), IQ offset, IQ imbalance, quadrature error and skews, is complex in optical coherent signal analysis.

在光相干信号分析中，即使很普通的测量也会相当复杂，比如测量 EVM（误差矢量幅度）、 IQ 偏置、IQ 不平衡、正交误差和偏移。
