Abstract In order to develop transfer standard of digital modulation quality parameters, a new method is proposed to set the modulation errors of the output digital modulation signal from vector signal generator accurately based on constellation diagram designing.Theoretical derivation, implementation and measurement points for comparison are presented.Stability of the developed transfer standard is verified by the statistics of the experimental data.
