摘要

这是第一份使用波形计量技术为WCDMA射频源的EVM测量提供国家标准可追溯性的方法报告。该方法采用采样示波器或实时数字示波器。初步结果表明，在95%置信度下，调制波形的均方根不确定度小于0.3%。

Traceable measurement of Error Vector Magnitude (EVM) in WCDMA signals

This is the first report of a methodology to provide national standards traceability for EVM measurement of WCDMA RF sources using waveform metrology techniques. The method uses sampling oscilloscopes or real-time digital oscilloscopes. Preliminary results indicate that the rms uncertainty of the modulation waveform, at 95% confidence, is less than 0.3 %.
