Hi Doktor Pyta
I will do it within my next free hours.
In the mean time I have found an always working Tektronix pulse generator 284:
The fast pulse, shown with a Tektronix 7904, plugin 7A29 for the fast pulse, plugin 7A19 for the trigger signal:
Above the entire fast pulse, below the trigger pulse, x-axis 200 ns / div, y-axis 100mV / div:
Above the fast pulse, below the trigger pulse, x axis 10 ns / div, y axis 100mV / div, 5 ns lead time (lead time)
Above the fast pulse, below the trigger pulse, x-axis 10 ns / div, y-axis 100mV / div, 75 ns lead time
Above the fast pulse, below the trigger pulse, x axis 5 ns / div, y axis 100mV / div, 5 ns lead time
Above the fast pulse, below the trigger pulse, x axis 1 ns / div, y axis 100mV / div, 5 ns lead time
Displayed rise time of the pulse is about 500 ps (Tek 7904).
