9402 - single pulse generation on two channels (with shift)

Hi!

I have Ni 9402 (4 fast DIO). Two channels are already in use, and I have to generate single pulse on last two.

I need a quite good precision in shifting "slave" channel. So, if the delay between first and second is programmed as 50 us, it should be around 50 us measured.

I know that I have to use triggers, but I have tried different possibilities (dummy channel as trigger too) and it generating only errors.

Can you help me?
