Pulse generation

[BZ]

Hi Everybody!

I have a 6602 board (high speed counter/timer) and I would like to know if
it is possible to generate pulses on the DIO or Counter outputs (5V TTL
level, 5microsec duration) at different intervals.
I saw that I can generate single pulses or pulse trains with the same delay
between pulses but I am wondering if I can have consecutive pulses at random
intervals (which can be as short as 5microsec).

Thank you
