Hello,

i have the PXI-4462 card and i will read the frequenz and the value from an audiocanel.
In the example i did't find an example.

Hello,

you must first read in your signal.

You get an data array.

You must analyse that array to get the frequenz and amplitude.
To do that you can use first the AutoPowerSpectrum()-function and then the PowerFrequencyEstimate()-function.
