NI Synchronization Custom Device

The NI Synchronization Custom Device synchronizes RT system time and PXI chassis clocks. This is accomplished by either reading the PXI chassis clock and setting system time, or by overwriting both system time and the PXI chassis clock when using an external time reference such as the free running clock of a Time-Based Synchronization module, 1588, 802.1AS, GPS, PPS, or IRIG-B. This functionality is commonly used for data sampling synchronization and offline data correlation analysis. For more detail and background on these topics, including sample data correlation files see: Building Synchronized NI VeriStand Systems and Time Correlating NI VeriStand Data Logs.
