Reply To: Real-time mode for narrow pulse and low duty cycle signal

Then what is the min. amount of points that each FFT does? Is it a fixed number? Or if it could be adjusted what’s the benefit of having FFT set to a lower amount of points?
In fact, I don’t care the activity changes in between pulses, because it’s certain that the signal is totally shut off when there is no pulse generated and the pulse’s central frequency won’t drift within such short period of time. That why I was asking if multiple pulses show up in the same sweep could do any help to the central frequency discrimination in the spectrum plot.
Could you explain more on this? Thanks.
