Dear SI Experts: I am trying to merge noise waveform to signal waveform. This may more clear to see the timing push out from coupling. But it seems no such kind of function in XTK, how do you do that if you want view a combined waveform? Noise gating function will help? Is there any example file for noise gating file? *.gsf file and *.ngf? Can anyone could provoide? Any suggestion is highly appreciated, thanks! Jack W.C.
