Just wondering if you guys can point me in the right direction for maybe a tutorial video or such on properly setting FFT parameters. I searched youtube a bit and it helped some, but its not quite there yet for what I want it to display. I have a Siglent SDS-1104X-E and Micsig D20003P probes, set to 200X. Trying to probe for harmonics/noise 5khz or less down to 3rd harmonic if possible, on 60Hz AC circuit. Yes I do know all about the dangers of working on AC, not new to it.
So far the settings I've tried are still showing too many lines that I don't believe mean anything useful yet and were not really changing with the system that I know to cause noise on the line turned on or off. Could the 200x attenuation make it harder for the scope/FFT to pick up these harmonics?
I'd like it to just show a bar graph essentially of the highest noise peaks present on the circuit. From what I had read about these scopes and FFT ahead of time it sounded capable of what I'm trying to do, actually doing it so far is a bit trickier.
thanks
