Code and Documents


The example demonstrates how to synchronize analog input and do buffered duty cycle/frequency counter measurements.

The goal of this VI is to synchronize Analog Input and Buffered Duty Cycle/Frequency Counter Measurements. This is done by generating a pulse train and using that as the sample clock source for two previously mentioned tasks. There is also another pulse train that is generated and physically looped back into counter measurement task so you can control what it is that you're expecting.

Steps to implement or execute code
To implement this example:
  1. Set the front panel parameter.
  2. Run the VI

To execute this example:

  1. Install the required software.
  2. Connect the DAQ hardware that supports the Counter and Analog Input features
  3. Confirm the connection with the MAX with TestPanel
  4. Open the VI and refer the Implement Steps

LabVIEW 2012 or compatible
NI-DAQmx 16.0 or compatible

cDAQ with C series Counter Input Module or compatible DAQ devices.
