5421/22 synchronization

[David L.]

Mark,

Are you using 2 different PXI systems? I just didn’t see your 5421 in the list above. I would also like to ask that you go back to the example using function generation, and make sure that the 5422 is the first device in the device list, and not the 5421. Lastly, I would like to ask for your email, as I will contact you directly and post back after we have a final result.

Oops sorry, its in slot #13.

You mean this one : niFgen_Arb_Synchronize_Example_(TClk)_2 different offsets.vi ""   yes I can confirm that the 5422 is the first device (called Dev8 and Dev9, where do these names come from ?).

Sure,   mark.hackett@analog.com

The final result on this issue is that the 5421 and 5422 have different analog paths. Since the cards have different amplifiers, parts, etc, there are different delays for each card,
and this delay varies with the speed. Below are pictures demonstrating how there is no delay when using two of the same cards.
