Waveform filter - Convert Waveform to 1D (sub)array of Waveform (Waveform(DBL)), not 1D array of double

[Desen]

Hi,

I am looking for a LabView waveform filter that converts Waveform to 1D array of Waveform.

In the vi attached, the aim is to compute power values from a csv file. The Labview example of Power & Energy (DAQmx).vi was used as a basis which requires the data from the csv file to be a 1D (sub)array of Waveform (Waveform(DBL)).

However, the Get Waveform Components filter I used converts the Waveform (Waveform(DBL)) into a 1D array of double [64-bit real (~15digit precision)],  not of Waveform (Waveform(DBL)).

I was hoping that there is an easy fix or possibly a magic filter that would do this.

The vi and csv file are attached for reference

Thanks a lot!

Hi Sivachandran,

I am experiencing a similar problem. Could you please attach the working vi?

Many thanks!

Hi Desen,

some basic LabVIEW stuff:

When your input is a waveform and you need an array of waveforms you should use BuildArray to build an array from your waveform!

(And please keep your discussion in one place!)

Hi Desan,

      I was experiencing that issue long ago and I figured out by using Build Waveform function the issue was sorted out. I have attached the vi for your reference.  

Hope it is useful to you.

Thanks,

Siva
