Expected meaning of RBW | How is the RBW calculated ?
Quote from David3542 on 23/05/2022, 13:03Hi
RBW: Resolution bandwidth
it means in plot each pixel in horizontal axis can define how much frequencyplease check this photo
from the plot i expect RBW is about 14.7Khz . but in legend wrote 20.5K
whats the reason of this difference?

The RBW depends on the used FFT windowing function e.g. "Hamming", "Flat Top" etc. and is calculated by the 3dB delta from the peak:
