Frequency Counter Reads 0

Updated Jul 31, 2018

Issue Details

I am reading the frequency of a digital signal using my cDAQ's counter.  When reading using edge counting, I receive an expected value.  However, when I read using the counter frequency, using DAQ Assistant, I receive a value of 0.  How can I get the expected value?

Solution

Try running the example under the downloads section of the NI-DAQmx: Continuously Measure Counter Frequency (Buffered-Large Range) page.  This example should allow you to read frequencies using your cDAQ's on board counters.  Do note that you may need to select the proper counter from the drop-down on the front panel of the example VI.
