Short pulse generator, part 3.

Last week I have finally put together the pulse generator described earlier. IXDD604 driver seems to work in a satisfactory manner producing ~ 30 ns pulses. Unfortunately I didn't had time to make any photos of the working setup, so for now I can show you only a single pulse measured using 150 ohm load (a regular power resistor for now).

Sweet, isn't it? There are several issues still to be resolved like oscillations after the pulse (so called ringing) and difficulties obtaining such pulses for different amplitudes and loads. The problem, most probably, is in the pulse shaper not in the power driver so I should be able to pursue this in order to get this device working better than it is now.
