Abstract
Disclosed are an Error Vector Magnitude (EVM) measurement method, a transmitter, and a computer-readable storage medium. The EVM measurement method includes: acquiring a cell configuration parameter from a control terminal device; generating a test data source according to the cell configuration parameter; obtaining a measurement signal according to the test data source; determining an error vector magnitude according to the measurement signal and a preset reference signal; and sending the error vector magnitude to the control terminal device, wherein the control terminal device determines whether there is any abnormality in RF indicators of the transmitter according to the error vector magnitude.
