The possibility of creating a calibrator of the parameters of signals with digital modulation, based on a signal generator of arbitrary form, was studied. A method has been developed for reproducing calibration signals with a specified value of the error vector magnitude (EVM) by the addition of normalized noise. A special case of the method, where amplitude and phase modulations area used as normalized noise, was examined. There has been experimental confirmation of the possibility of transmitting the units of amplitude depth and phase deviation, respectively, from the National Primary Standard of the unit of frequency deviation, GET 166-2020, and the National Primary Standard of the unit of amplitude depth of high-frequency oscillations, GET 180-2010, to a calibrator of signal parameters with digital modulation.
