Generate a delayed pulse with analog trigger(2)

[cooler]

Hello Filipe:
For each buffer iteration,the AO updates many times,each update corresponds to a TTL signal routed to RTSI.If I use retriggered pulse generation,it generates many pulses on every TTL edge in one iteration.But what I want is to generate a pulse on the first edge of each iteration only...
sorry for bother you so many times...
(P.S If I just comment your answer,can you see the comment?)

If you will need to have a AO updating more than once, you will need to generate a pulse train and that pulse train will need to be routed to be the AO update signal. Keep in mind that each active edge of the AO update will update the AO. So, you will need to set up the counters in a way that your timing needs are met, by doing a retriggerable single pulse or pulse train generation, depending upon your needs.
