3 channel pulse generation

[sperelat]

I need to generate pulses in ~microseconds

in my lab.

The pulses must be generated via 3 channels and

I want to control width and delay of them to change

time overlaps.

I tried it with Labview..but analog output was too unstable,

and digital output needed external clock.

(Function generation input didn't work)

I'm considering microcontroller timer/counter pin s..

but I don't know exactly if microcontroller timer pins

can be applied in this way.

Does any one know circuit or device that can be

adopted for this kind of work?

If I understood you correctly, you can do this with the Dino DG535 (it is a
design from 1986 ;-)) from Stanford.
