You probably know more about this than me but I always use 4 to 8 resistors in parallel, measure across 1 of them and then multiply times the number of resistors in a pulsed circuit.

I don't think 1 resistor is going to do a precise enough job of phasing the current to voltage to tell the difference between COP <1 and COP >280.   

If you can explain to me how to hook 8 resistors up in parallel and then measure across _just one of them_, with a 20 MHz scope, I'd appreciate it.

You have in the past 2 pages made claims about making a self-running device, OU and whatnot. I say you cannot do it. So prove me wrong by showing something, like measurements, on some device that you have actually made using your theories, er, conjectures.

Right now I have a Tektronix 2230 DSO.  If you can explain how to do trace multiplication, that would be very helpful -- and if it can do a live integral that would awesome. 

Hah... proved me wrong about early Tek DSOs... see, it's easy... when I'm actually wrong, that is !

The Tek 2230 can't do trace math except the usual addition and chopping. It is "barely" a DSO at all. But if it has the appropriate GPIB or serial interface option, you can run Tektronix's "WaveStar" software and do the math on stored traces in there. But it sounds like you are going to have to do it using the manual method I outlined above. It's really not too hard. At least the 2230 has cursors, so you can get precise values to work with !!

I also have available a Tektronix 3032 (300 MHz bandwidth)... How about that?

Good! now you need to learn how to use it just like your buddy Lawrence the Clown.
