FFT maximum peaks

I have a slice unit to capture vibration of an equipment. I am currently using FFT analyzer (attached is my channel setup & FFT screen shot). In the measure window, the markers give me top 5 freq & rms amplitudes. I want to extract this information, so that I can write it to a file in real time basis ( eg every 1 sec) or later push it through opc ua to other machine.

I tried basic and array statistics from math, but i can only see max and min values. Also it does not give me the freq.

The FFT markers and their table is a visual control and does not create a math channel that you can export or write it to a file

in real time.

If you are interested in the frequency position of the maximum peak, you can use MAXPOS function in our Formula math.

Please let me know if you have any additional questions.
