Abstract

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 %.
