Hey guys.
I built a rotary converter to power my newest tool, a 36" bandsaw at 550 volts 3 phase.

I am interested in fine tuning this sinusoidal voltage and correcting waveshape as is possible.

Is there an instrument which would allow viewing of the waveshapes that is reasonably inexpensive?

I see quite a few oscilloscopes for sale at auctions but don't know what to look for.

Also if the waveshape can be displayed will the harmonics also appear?
