Re: Continuum mode

Figure one signal is present, a unit gain (0 dBfs)
sinewave. Without shaping it will appear in one or two bins
ideally. You take the power level for all bins within the
bandwidth Y and sum their power, not voltage, of course. It's
independent of the X bandwidth. Scaling would be the same as you
use for the spectrum display.

Or take the FFT array of values, multiply each cell by your calculated IF filter shape, pick a bundle of values around the center of the filter to get a nice power of two bin count, take reverse FFT, pseudo power = I^2 + Q^2, Nominally ir should have scaling to make that come out as 0 dBfs for that single sinewave signal. Then the real world should sort of fall out of what you have with no further work. (Yes, I am fixated on I^2 + Q^2 pseudo power.) {O.} On 20220317 03:45:40, Simon Brown
