Oscilloscope: Square wave view while in FFT mode?

Are you getting audio interference in a USB sound card or something like that?
tinkerbotstl:
I was specifically hoping to avoid all of the comments about the dangers of probing mains. Just need to see the harmonics on the AC line.

Well your original question made no sense at all, because there's no such thing as a "square wave view", if you want to look at the frequency spectrum of a square wave, you feed a square wave to the scope, the FFT on the scope displays the spectra of whatever signal you put into it, nothing more.
