11.17.6 Time Domain Power Measurement
In the following example, the mean carrier power of a signal with 300 kHz bandwidth at
100 MHz is to be determined. In addition, the peak power, the rms value and the stan-
dard deviation are measured. To do this, the time-domain-power measurement func-
tions are used.
