Interpreting FFT data non graphically

[UH Researcher]

I am performing an FFT (real FFT.vi) on real time data in order to measure the Frequency and Amplitude of a pulse between 1 and 3 Hertz. I can produce a graph of the FFT spectrum with proper scaling, and I can see this pulse to the right of the DC peak. However, I also would like to use the data to find the pulse period and use the amplitude for other analysis.
How can I extract this information from the cluster containing the FFT and scaling information, and use it for frequency and amplitude calculations?

Hi,

You can use the peak detector.vi to detect the location and amplitude of peaks in your fft signal.
