Hi,

"VIDEO TAPE"!!!

If you have a camcorder or such contraption, point it at the scope and 
hope!!  You might then be able to frame by frame the scope's screen on the 
camcoder and get a picture off it "somehow"...

I trust you can "trigger" on that SOB going off ;-)))))  Like a foot long 
length of wire off the trigger input should "pickup" the "cosmic wave" off 
it real good... :o)))

The beckman HV probe might only have a <300 Hz bandwidth, but try anyway ;-))

Cheers,

         Terry
