Webb14 feb. 2024 · Normally, the density part of PSD means you're getting power per Hz, so you would multiply the PSD values by the bandwidth of interest, and see the total power in that frequency range. Your spectrum specifies RBW per 100kHz, so it may just be the number of bins, which is the frequency range divided by 100 kHz. – pscheidler Feb 9, 2024 at 18:34 WebbPower spectral density is mostly used to understand the amplitudes & frequencies of signals (oscillatory) in our time series data.
