The number of neighboring bins on either side of a frequency depends on the FFT windowing technique as follows:
These neighboring bins are always included for the fundamental.
For harmonics and spurs, it is user configurable in the HSDC Pro menu option – Notch frequency bins. If Harmonic/Spur Power Calculation method is Integrate, the neighboring bins are included for the harmonics and spur.
If Harmonic/Spur Power Calculation method is Don’t Integrate, the neighboring bins are excluded for the harmonics and spur.
