I've never been able to find a Victor schematic, but the datasheet for the Jag's opto-isolator says it has an absolute maximum continuous current rating of 60 ma for the input.
The cable I am using for my test equipment here delivers about 5.6 ma to the Victor during the pulse, and it works fine.
Can you post a picture of your scope's current waveform?

I won't be able to get back into the school till later tonight or tomorrow, but I'll get that to you as soon as i can. Next time i'll try putting a larger resistor in line to lower the current down to 50mA and see if that changes anything. I just hope i haven't damaged the victor.
