I have a Tektronix 2235 scope.

I also have a hell machine for making high voltage discharges.

I also have a Beckman 50kV high voltage divider probe for high voltage
linemen, similar to this.

What I would like to do, is capture on the oscilloscope screen, the
waveform of the occurring discharge. I want to keep it for a while to
be able to get to the scope and take a photograph. 

I only used my scope before for watching continuous waveforms, never
for one shot.

I guess my main question is does anyone know how to trigger the scope
by the discharge and then let it keep the waveform on the screen, is
that even possible with 2235.

thanks
