PCI-6251, Analog output trigger with the other analog output available

[Manohar]

Dear friends,

I want to do phase locked PIV measurements. to do that with a frequency generator and with 2 triggering device.. this is possible ... but there is a small problem with availability of both the triggering devices at once. for this reson i want to write a small code in labview which can give me a trigger.

I have modified the frequency generator example(inbuilt) of Labview but i am not able to trigger the other analog output channel with this frequency generator (analog output).

I can generate, simultaniously, different waveform at different chennal, but I am not able to seprate them..  I think this is a bit confusing (even for me to explain..)

may be the attached block diagram will help to explain this batter..

Thus
1) I should generate a contineous signal with certain frequency and amplitude (No problem with this) in AO-0

2) Gives trigger at '0' crossing + phase shift  (unable to trigger AO-1 with AO-0)

3) should wait for 100ms (laser property)

4) search and give second trigger at next '0' level crossing (of signal) + phase shift



Please help me with this. And if there any example i can refer please suggest me.. I searched through the labview example but nothing is clear for me..

And as you might have guessed I am new with labview.. I am using Labview 8.2 and PCI-6251

Thanks in advance
