Using Signal-Based Synchronization in NI-Sync

Signal-based synchronization is characterized by physically sharing a combination of clocks and triggers to synchronize data acquisition and instrument control. Using a signal-based synchronization method, you can route clock and trigger signals throughout the system with niSync Connect Clock Terminals and niSync Connect Trigger Terminals. Once you connect clock and trigger terminals, the signals are used to synchronize devices and modules using the terminal routes you established.

Using the signal-based synchronization method, you can perform the following actions:

The clock signal(s) used to synchronize devices in the signal-based synchronization method can originate from an external clock connected to ClkIn, a DDS signal created with a signal-based timing and synchronization module, the backplane clock of a PXI or PXIe chassis, or the oscillator of the NI-Sync device.

Signal-Based Synchronization Phases

The signal-based synchronization method can be broken down into the following phases:

Signal-Based Advanced and Utility Functions

Functions and VIs that do not fall into the above signal-based synchronization phases are considered Advanced or Utility functions. You can access the Advanced palette by selecting NI-Sync»Advanced from the Functions palette, and the Utility palette by selecting NI-Sync»Utility.
