Yes, that is the function generator I have. vc2002 , wasted $$$

frequency doesn't have strength, I mean, you can call it that way. It's value. VFDs operates on small frequency, up to 50 (or 60) Hz. They are primarily used for controlling the speed of motors, to start them without stress and is going from 0 to maximum (50 or 60).
If you want to play with those sparks like in tesla coil, you need something with high frequency, few MHz.
and Paz's idea sounds interesting
