A certain spectrum analyzer measures the average power delivered to a calibrated resistor by the individual harmonics
Question:
A certain spectrum analyzer measures the average power delivered to a calibrated resistor by the individual harmonics of periodic waveforms. The calibration of the analyzer has been checked by applying a \(1-\mathrm{MHz}\) square wave and the following results reported:
The reported power in \(\mathrm{dBm}\) is \(P=10 \log \left(P_{\mathrm{n}}ight)\), where \(P_{\mathrm{n}}\) is the average power delivered by the \(n\)th harmonic in \(\mathrm{mW}\). Is the spectrum analyzer correctly calibrated?
