摘要

本文介绍了一种基于信号数字处理的误差矢量幅度(EVM)测量方法。提出了si系统主单元标准跟踪测量的透视方法。为了减小EVM测量的误差，本文考虑了采用数字示波器的EVM测量方法。测量方法的计算绝对误差为0.1%。这比EVM测量工具的常见误差值要小得多。

Methods of EVM Measurement and Calibration Algorithms for Measuring Instruments

The article describes a method of Error Vector Magnitude (EVM) measurement based on signal digital processing. Perspective methods of measurement with tracking against standards of SI-system main units is presented. In order to reduce the error of EVM measurement, the article considers the EVM method using a digital oscilloscope. Calculated absolute error of the measurement method is 0.1%. This is much less than common error values of EVM measuring tools.
