How do I use the "ZeroPhaseFiltering" function in Measurment Studio fo a Butterworth low-pass filter. I don't know how to get the "reverseCoefficients" and "forwardCoefficients"?

I'm not sure if there is anything built in to Measurement Studio. However, I think if you filter the signal, reverse the data array, filter it again, reverse the array again, you have a zero phase filter. Whatever phase shift took place when passing the data through the filter should be reversed if the samples are reversed. I haven't tried this but let us know your results if you do.
