Optical cables are standard equipment with fluke scopemeters when you opt to buy the scopeview software with your scope.
BTW there is also an open source version of the lead and software available I lost my optical lead and didn't fancy paying Fluke prices for a replacement .

thanks Martin somone pointed me to this web page earlier but its just a low baud rate IR type connection i dont have a fluke scope, its a pc based conventional o-scope so i need full 1.0 or 2.0 usb.

Well, gave it a shot! Piggy backing two of the cables does in fact transmit usb to usb. However, you would need to change one of the usb ends or use an adapter. Does the trick but if it doesnt do it at the speed you need, no good i guess. Anyway, i hope you get it figured out! Maybe i will be making a setup like yours for myself!!

Yeah, Doctor Electrons i am trying to get my CVD finnalized and operational as soon as possible. i have the first prototype fully constructed, will post pics on that thread soon. my design no longer uses a op-amp, only a compensation BNC probe so look at my current work.
thanks for your help all! i will try to get this sorted out. First the best thing i can do is get both ground planes to near the same potential, then attach them to each other. then the isolation is a non-concern if all is star-grounded. second, if i cant get one ground potential between all, then i will use wireless usb! a great idea since i can place the transmitter at (5m) from any RFI-EMI source. then my laptop just has to be somewhere in the room nearby.
And yes for personal and academic work you are free to use my work and copy as is, so long as i get a citation or short blurb on your webpage or published work, i just want a mention and credit for whats mine. i will help and advise if i can.
Next if your a big government agency, or a fat corporation then i want money, college isnt cheap, anyone who steals my work, patented or not--is dead to me. if you get your own people killed from bad HV work, dont come crawling back, offering me back pay for anything you stole.
Finnally, fair play.... i dont steal from others, and i mention those who contribute.

here is a modification i will test.
I have totally reengineered my setup,now there is only one ground plane and thus this USB cable may work.
As seen in the pic, the o-scope is on the left, the laptop on the right, in the center is the "T" shaped tap to allow a star ground for the USB cord.The problem with this setup is that the quality of the two USB connections determines the quality of the ground.
Anders M. the Si8xx series uses radio waves to transmit data not magnatism right?
