SNR is calculated as the difference between integrated fundamental power (fundamental power, including its neighboring bins) and the noise power.
The noise power is calculated, excluding the fundamental and its neighboring bins, harmonics, and custom notch frequencies. The neighboring bins of the harmonics are excluded if the GUI menu option - Notch frequency bins - Harmonic/Spur Power Calculation method is Integrate.
