How get the frequency of a signal?

[dboulay]

Hi,

I'm a beginner with Labview. I use a CRIO-9002 with the 9102 chassis and a 9215 module. I want to measure the frequency of the input signal. I use Relay.vi to clean the signal but I don't how to proceed to get this value.

Somebody can help me ?

Thanks

In the Analyze>Waveform Measurements pallet you will find Extract Single Tone Information, SINAD Analyzer and Harmonic Distortion Analyzer.  They will all output the detected fundamental frequency.
