How to use frequency counter

[Silverwolfman]

It's my first time start to use frequency counter based on USB-6212 under labwindows,  could any one point me to the example I could refer to? 

the frequency we try to measure is 512hz, 1hz, I assume it should be Pulse-Width Measurement by single counter application.

Thanks,

If you need to measure frequency you should use frequency or period measurement. Examples for these measurements are installed on your system together with DAQmx: open CVI and run Help >> Find examples... menu function. Navigate in the tree in the middle of the Example Finder window up to Hardware Input and Output >> DAQmx >> Counter Measurement >> Digital Frequency or >> Period or Pulse Width: there you'll finde some examples on the available solutions.
