Approximate Frequency Measurement with USB-600X Simple Edge Counter
PrintThe operation is as follows:
Steps:
1. Create empty task
2. Create a Counter Input channel to Count Events. The Edge parameter must be set to increment on falling edges.
3. Call the Start VI to arm the counter and begin counting. The counter will be preloaded with the Initial Count.
4. The counter will be continually polled until the Stop button is pressed on the front panel. This will give both counter readings as well as approximate frequency readings.
5. Stop the task
6. Call the Clear Task VI to clear the Task.
7. Use the popup dialog box to display an error if any.
