Abstract
A method is described for measuring the modulation error in digital modulated high frequency signal, whose amplitude and/or phase is digitally distorted according to a predetermined function, in particular limited by a given clip factor, in which the signal to be measured is compared with a locally generated reference signal that was generated by taking the predetermined distortion function into account.
