Hi everybody,
As I see in the FPGA and Real time programming, timestamp concept and its objects work just in milliseconds precision and if we need more accuracy (micro or nano seconds, especially in FPGA), we can use Tick Count object and implement Timestamping by hand. Is that true?

Hi,
Yes you are right. You can program the FPGA with ticks using the Loop timer. Each tick equals 25 ns. Here are some useful documentation:

Finallly, the cRIO Full developer´s guide has useful information about this. http://www.ni.com/pdf/products/us/fullcriodevguide.pdf
