Abstract
A measuring device for measuring the envelope power and the mean-power value of a high-frequency signal. The measuring device includes a detector for detecting the high-frequency signal and for generating an analog detector signal, an analog/digital converter for generating a digital signal and an evaluation device for evaluating the digital signal. A dither supply device for the supply of a dither signal is disposed between the detector and the analog/digital converter, and a dither elimination device for eliminating the dither signal is disposed between the analog/digital converter and the evaluation device. The dither supply device supplies a different dither signal for the measurement of the envelope power than for the measurement of the mean-power value.
