PXI 5411 sin wave burst plus timing

[PJS]

I have a PXI system with a 5411 ARB card and a 6259 MIO card.
Here is the issue.
I need to:

1.  generate a sin wave pulse at 16MHZ...
2. This pulse initiates at T0 plus Tn from a trigger pulse generated by the AO of the 6259 (needs to be as short as 1mS and as long as 3000mS-repeatable and guaranteed)
   
3. This duration of this pulse is Tx (can be as short as 1mS up to 1000mS again repeatable and guarenteed)

My problem has been that the timing of Tn and Tx is at the mercy of the computer as ranges up to times as great as 1000mS.

I know there is something simple that I am overlooking... but for the life of me, I have not been able to find it.
Thanks,
Paul

What I am looking for is the ability to Gate the pulse using a trigger line from the PXI-6259.
Anybody?

Hi Paul,

I'd like to clarify a couple points in your post to make sure I understand your application correctly.  It sounds like you want to generate a trigger pulse on the 6259 - is this using the counter or analog output?  You also mentioned that you wanted your start trigger and reference trigger to be user-defined, but you are only getting 1000ms accuracy.  This may be occuring because you may be using software timing. 

It sounds to me like you'd like to use a digital trigger from your 6259 to start your acquisition, then specifying the number of samples to generate to control your Tx time.  I may be missing something that you're trying to do in your application, so please reply with more details on your application if possible. 

Thanks!
