Abstract

A measuring device for measuring a signal with a first component signal and at least one second component signal comprises a high-frequency processing device, which is embodied to mix the signal in order to form an intermediate-frequency signal and to digitize the latter in order to form a digital composite signal. The measuring device further comprises a digital mixer, which is embodied to generate a first digital composite test signal and a second digital composite test signal subject to a displacement of the frequency of the digital composite signal. Moreover, the measuring device comprises a digital filter, which is embodied to filter the first digital composite test signal in order to form a first digital test signal and to filter the second digital composite test signal in order to form a second digital test signal.
