摘要: In a method for checking the functionality of a mixer, the mixer is supplied with a high-frequency signal and a high-frequency comparison signal in order to generate a baseband signal. The amplitude of the high-frequency signal is modified as a function of time. A direct-current voltage component of the baseband signal which is output by the mixer is analyzed to determine the functionality of the mixer.
