6602 phase accuracy

[del-donno.1]

Hello,
    I'm wondering if anyone can comment on the phase error I can expect when using three channels in DMA on a PXI-6602 card.  I'm interested in doing transmission error measurements using encoders attached to a 6602 card, and need to be certain the channels are measuring at the same time, or with an extremely low phase error.  I looked through the 6602 manual and the support articles on ni.com, but was unable to find the information I was looking for (unless I missed it).

Thanks in advance.

Hi,

I believe what you are referring to is phase locking.  You can find information on this in the 660x User Guide on pages 3-17.

I also found a helpful Knowledge Base on Phase Locked Loops. Pay attention to the links on the bottom of the article, they are helpful also.

I hope this helps!
