Description
Summary: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.
