can someone please show me how to do a multi acq average?

[zskillz]

I have tried my hardest, but I think I'm missing something fairly simple here.

I want to average multiple records, but I just can't figure out how to do it.  I've attached a sample VI that I would really appreciate if someone could edit and make the top graph show the preprocessed data and the bottom graph show the processed data.

thanks a ton in advance,

Hi zskillz,

It looks like you've modeled this after the shipping example "niScope EX Advanced Measurement Library.vi".  You currently have the polymorphic vi option of "Scalar 1D Double" selected.  The polymorphic option of either "1D Cluster" or "2D DBL" (Array>Multi) has to be selected with a waveform graph indicator for the data output because the "Multi Acq. Average" returns an array and not a scalar value.  Also be sure to wire the "array measurement" control into the appropriate input terminal of the measurement vi.
