How to Export the Internal Analog Input Sample Clock

Identify a Valid Terminal for the AI Sample Clock

1. Open Measurement & Automation Explorer (MAX).
2. Select your DAQ device under Devices and Interfaces.
3. Open the Device Routes tab.
4. Locate the AI Sample Clock source in the routing table. The figure below shows the Device Routes tab for a multifunction DAQ device.
5. Identify which PFI terminals can accept the AI Sample Clock signal.
   • Green cells indicate a direct route that does not consume device resources.
   • Yellow cells indicate that internal subsystems are used to make the connection.
6. Choose a PFI terminal with a green route when possible.
   In this example, PFI7 is the preferred option because it does not consume additional device resources.
    

Route the AI Sample Clock to the Selected PFI Terminal

1. Open your NI‑DAQmx task in LabVIEW.
2. Place the DAQmx Export Signals VI on the block diagram. You can find it in the Functions Palette at: Measurement I/O » DAQmx – Data Acquisition » DAQmx Advanced Task Options » DAQmx Export Signal  
3. Configure the DAQmx Export Signals VI to export the AI Sample Clock to the selected PFI terminal.
4. Run the task to output the AI Sample Clock on the chosen PFI line.
