Autocorrelation function

[milliars]

Hello 

I need to determine the autocorrelation function of a waveform, which of course involves time integration of the waveform with a time delayed version of itself. 

Is it possible to display a time-delayed version of a signal on a Math channel? I am thinking of then writing a script to adjust the delay, acquire a series of delayed waveforms and then calculate the autocorrelation function.

Thanks

Hi @milliars

The WaveForms beta version adds Lock-in amplifier as Math channel option:
