How do I record three input signals in one output file?

[Brendan Shanley]

Hi,
I am trying to take amplitude data from three wave forms (from a three phase supply, for example) and output them into one text file, with a column for each phase.  All I have been able to do so far is get a sum of the signals, which is not what I'm looking for.

Thanks!
Brendan

Why don't you just combine the data into a 2D array and append it to your file ?

That seems to work well...  Do you have any advice for getting phase information out of the waveform data in addition to the magnitude data?

Thanks,
Brendan

There is a vi, in the "Analyze > Waveform measurement" subpalette named "Extract single tone information" that returns the phase info.  Try it...
