Help generating a waveform...

Yes, I'm familiar with Ohms law. It may actually be around 50V for this device, I might have mistakenly referenced the output voltage of another(I've been looking at ALOT of different CES schematics...)

I was thinking of going the PWM route with this, maybe that's not the best option but I've got almost everything that I need minus the transformer. I was hoping to use what I had on hand.

I'll probably need to get ahold of a DAC to do the job. Also, why would a small transformer make things more difficult? I have to go from DC to AC, do I not?

The idea, I think, is to pulse this particular waveform .5x/sec, 1.5x/sec or 100x/sec.

"The MET device is a precision technology which generates a modified square, bipolar waveform of 0.5, 1.5, or 100 pulses per second (Hz), at 50 to 600 microamperes (1 μA is one-millionth of an ampere), in a 50% duty cycle."

Perhaps I'm missing something, as usual, but can't the aforementioned waveform be sped up or slowed down to allow for pulsing at the above frequencies?
