measure the frequeny and cadence of a tone

[Kumar]

I would like to measure the frequency and the cadence of alert tones from the two-way mobile radio. How do I go about doing it. I have a Multifunction 6035 E series card with the accessories. I also have the thge side connector cable of the radio to tap the tones.

Kumar,

In general what you have to do is acquire the signal through your DAQ board and then use some of the Analyze VIs for doing the rest of the signal processing and analysis.

I found some pretty good places where you can get and idea on how to implement your application, here they are:

Tutorials: Fast Fourier Transform


Spectrum Analyzer


I would also recomend to visit ni.com and make a search for "spectrum analysis". Hope this helps!
