Synchronization Modes

The 32-bit counter counts up or down synchronously with the Source signal. The Gate signal and other counter inputs are asynchronous to the Source signal, so the sbRIO controller synchronizes these signals before presenting them to the internal counter.

Depending on how you configure your controller, the sbRIO controller uses one of two synchronization methods:
  • 80 MHz Source Mode
  • External or Internal Source Less than 20 MHz
