DAQ_Synchronization Library VIs route signals between specified source signals and output terminals for the given DAQmx Task.

Note For synchronization examples that use the Synchronization Library, refer to the Backplane Synchronization Example sequence included with the PCB Assembly Test Toolkit for LabVIEW or any included example automated test sequence configured to route a DAQ signal to a second DAQ device.
  1. Retrieve the DAQmx Task from any PCB Assembly Test Toolkit DAQ library Initialize VI.
  2. Pass the DAQmx Task to the DAQ_Route synchronization signals VI.
  3. Configure the Routing paths input, which specifies the list of paths between exported signals and output terminals where routing actions are performed.

    Refer to the Device Routes table in NI Measurement & Automation Explorer to determine eligible signals to route for the target device.

    In TestScale, certain internal signals can be routed and exposed to external PFI Lines. For more details refer to Digital Routing in the TestScale Features manual.

    Note The routes created by this VI are embedded in a task. Once the DAQmx task is committed, the route is committed to the targeted device. When the task is cleared, the route is unreserved. Refer to Task-Based Routing in the NI-DAQmx User Manual for more information and refer to Signal Routing for general information.
    Note The source signal and output terminal can be on different devices as long as a public bus, such as PXIe backplane slots or the TestScale backplane, connects the devices.
  4. Wire the updated task from DAQmx Task Out.
  5. Perform additional task configuration using any PCB Assembly Test Toolkit library Configure VI.
  6. Close the task using any PCB Assembly Test Toolkit for LabVIEW library Close VI.

Best Practices

  • For faster measurements, set the maximum sampling rate possible for the given Sample Clock Source input and assign a smaller Number of Samples to capture.
  • For better resolution, increase the number of samples (for example, 1000 samples).
