Hi all, I am pretty new to LabView and data aquisition. Sorry to bother you all. I have a question: "I have recorded a distorted waveform using digital oscilloscope. The format of the file is .bmp i.e. Paintbrush picture. I want to perform the FFT analysis of this waveform. How can I do it in Labview????? I already have the magnitude spectrum using the FFT mode of the oscilloscope, but I need to get the phase spectrum as well so that I get the phase angle for each of the harmonics. Could you be very kind to guide me in this regards????" Thanking in anticipation. Best regards,Haroon

Instead of the bundle, use a Build Waveform function. Out of the scope function is 'waveform array' and 'X increment'. You only need those. Wire the array to the Y input and x increment to the dt input.

Thanks for the guidance and a brilliant idea. It seems to be working okay now
