Hi Ashraf, that's no real power -- it's the absolute magnitude of the FFT in each bin, in dB relative to 1. If you need numbers in real power (ie. numbers on your screen that directly relate to a signal power in real physics), you will need to calibrate your system with an external signal of which you know the (physical) power of. This will only apply for a short time, for a given configuration of frequency, sampling rate, gain. I don't know what you mean with m.data, but I think you're on to nothing correct.
