Patent ID: 8102171

Claim:
A measuring device for measuring the envelope power and the mean-power value of a high-frequency signal comprising: a detector for detecting the high-frequency signal and for generating an analog detector signal, with an analog/digital converter for generating a digital signal, with an evaluation device for evaluating the digital signal, wherein a dither supply device for the supply of a dither signal is disposed between the detector and the analog/digital converter, wherein 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, and wherein, for the measurement of the envelope power, a first dither signal is supplied, which is not changed during the recording of measured-value series consisting of several measured values of the envelope power, but is varied between the recordings of the measurement series, and wherein a second dither signal, which is varied continuously, is supplied for the measurement of the mean-power value.
