Fourier Transform, Fourier Series, Discrete Fourier Transform (FFT) have differentscale factor to convert to one another. Measured signal amplitude is close to Fourier Coefficient (Fourier Series) you may multiply 2/N/dt to FFT to know its Fourier Coefficients. (I am not sure, please refer signal processing texts) To get a reliable result, include as much averages as you can get a stable result of windowing. |
