PXI 5433 2CH: Generate same arbitatary wfrm on both channels with adjustable delay

I want (need) to use the 2 CH of my 5433 to generate the same signal (continously) with an adjustable delay. 

 

This example code (buggy IMHO) 

https://forums.ni.com/t5/Example-Code/FGEN-TClk-Adjustable-Delay/tac-p/4457718#M15566

 

show a way to do it, but intended to use with two different devices using TClk sync . As far as I understood the 5433 manual TClk Sync can't be used with two tasks on one 5433. Is my asumption rigth, that there is just one TClk Sample Clock delay for both channels?

 

Within 1/400M s = 2.5 ns increments one could shift by sample , however will the script/DMA engine read one wfrm for both channels with arbitary distance?

 

For smaller increments (or generally)  I could generate and write two wfrms (DFT,shift phases, IDFT)  if both fit into my memory .. 

Or use a power splitter and different cable length, what is so last century 😉

 

Other ideas?

What is your end goal? what is the range of offset and resolution do you intend?

Range 100 ns maybe up to 500us

Resolution 1ns fine 100ps better

 

Tendency is towards two wfrms ...
