FGEN Arbitrary Waveform Normalization

[William.Maier]

I have been using the "Open Front Panel" option of the FGEN Arb Express VI to help me construct my own Arbritrary Waveform VI.  I noticed in the Express VI, there is a piece of code that appears to normalize the waveform.  I think this is affecting my output in undesirable ways.  Is this code necessary?  I am using the 5421 which has a 12V limit, so I don't think I need to normalize to 1 volt.

Thanks in advance for any advice.

Forgot to include the image and I couldn't see the edit option for some reason on the opening post.

Sorry for the bump.

The normalization has to be there. The NI-FGEN Create Waveform (WDT).vi needs to have the input waveform in the range of -1 to 1. Use the gain parameter to get your signal to the amplitude that you need.
