Oscilloscope: Square wave view while in FFT mode?
tinkerbotstl:
Howdy,
I have searched the Hantek 5072P scopes menu's and settings, the manual with search tools, google, youtube - asking the same question, and asked the same question on hantek forum, all with zero results.
Full question:
How do you switch to a square wave view while looking at a sine wave with FFT?
Please see the following pic for exactly the display view I am looking for:

You can even see a guy on youtube do it with the same scope at 0:44 seconds into the video:
Thank you ahead of time :)

Great question, I do not know how to do that either, so I'll be watching this post.
PA0PBZ:
If you want to look at the FFT of a square wave you obviously have to feed a square wave into the scope.
tinkerbotstl:
But if that is the case, can you please explain to me what's happening in the video I posted, he's looking at a sine wave in fft mode, then he switches the view of the same wave? It's the same wave he's looking at, I think? The click you hear in the video is the oscilloscope switching functions but the shape of the wave is the same only after he switches functions you can then see the harmonics and he States something to the effect of here's the square wave view.
Wimberleytech:
The guy in the video is (most likely) driving the scope with a signal generator that outputs a sine or square determined by a switch on the SIGNAL GENERATOR. He simply turns a knob or flips a switch, or punches a button on the signal generator to change from sine to square. Nothing changes on the scope
