PWM Frequency reading with USB-6341

Solved!
Go to solution

Hello,

I'm programming a test software for an EV Charger, and one of the things I need to check is if the PWM generated by te board has a frequency between 970 and 1010 HZ.

 

Is there any way I can measure this with my USB-6341? I'm at a loss because I usually just check voltage levels with analog readings and the state of different digital inputs for the other test softwares I've developed.

 

Thanks in advance!

The USB-6341 offers 4 "general purpose" counters, so you can easily measure frequencies using your DAQ device!

Thank you that's nice to hear I wasn't even sure what to look for as I'm relatively new to this, do you happen to know where I could find some example to check on how to configure a counter?

There is one place in LabVIEW where you find example code: use the ExampleFinder in the help menu!
