Electric power is the rate at which electrical energy is transferred by an electric circuit. The SI unit of power is the watt (one joule per second). Use this tag where power is a primary concern for the design under discussion. Use the "low-power" tag when that applies.

Active power output calculation of hf generator unit based on measured volt acorss a load
.
$$
So for your power calculation then,
$$
P = \frac{V_{RMS}^2}{R}=\frac{160^2}{500}=51.2~\text{W}
$$
I hope this makes it clear that for more complex waveforms calculating the RMS voltage is not quite …

How to calculate total power from spectrum?
For a band limited power spectral density \$S(f)\$ to obtain the total power all you need to do is integrate over the spectrum. … The first step is to convert your power measurement into a linear scale,
$$
S_{lin} = 10^{S_{dBm}/10} \qquad (mW/Hz).
$$
Once you have your power in a linear scale you can then integrate over the total …
