摘要

A method for measuring the modulation error on a digitally modulated high-frequency signal by comparing the signal to be measured with a locally generated ideal reference signal,wherein, for the measurement of signals, the amplitude and / or phase in accordance with a known function is distorted, this known distortion function also in the case of the local production of the reference signal is taken into account accordingly,characterized by the,that for the measurement signals whose amplitude is limited to a predetermined clippfaktor, this predetermined clippfaktor also in the case of the local production of the reference signal is taken into account accordingly.
