I am going to design a digital monostable for use in various projects.
I will use digital delay lines DS1023, these come in various flavours 250 pS, 1nS, 2nS, 5nS
i will design so the 1nS,2nS can be used.
If 1nS chips are used then the monostable will allow a pulse width of 0-512nS in steps of 1nS
if 2nS chips are used then the pulse width will be 0-999nS in steps of 2nS
I will allow this to be set in software for display purposes and then it's just a case of plugging in the chosen chip.
everything will be through hole for easy construction.
A 3 digit 7-segment display will show the set pulse width.
The value will be set using a rotary thumb encoder, a switch on the shaft can be used to store the current setting for instant power up value.
I will provide a fast ttl buffer stage for the output pulse.
Input supply voltage 7-30V, on board 5v regulator.
Anything else people require or any other suggestions and i will see what i can do.
What plug does everyone want with the output pulse to appear on BNC???
