Measuring frequency with CompactRio

$

Dear All

 

I have an anemometer that sends digital signal. I try to analyse the signal to determine the wind speed.

I have a NI cRio 9024 and NI 9205. When I connect the anemometer, it gives me back voltage square pluses (see attachment). I wonder if I could transform this to readings of frequency because it is linear to the wind speed.

 

I tried to follow the link below, but my module does not have the Specialty Digital Configuration option

or I should have another NI module that could measure the frequency of the signal directly?

I would appreciate any ideas or suggestions. Thank you so much!
