A method to traceably calibrate Wideband Code Division Multiple Access (WCDMA) Error Vector Magnitude (EVM) contributions of a source or receiver is described using a Real-Time Digital Oscilloscope as the reference receiver. The results and uncertainties are presented for a receiver calibrated using four WCDMA sources from different manufacturers. The weighted mean EVM of the receiver at 900 MHz is 0.35 ±0.03 % at 95% confidence. Measurement results at 1780 MHz and 2510 MHz are also reported.
