Place the vi program on this site. There are two waveform channels (CH0 and CH1). 1) I performed FFT processing on two waveforms, but in the FFT graph after processing, CH1 is displayed as CH0 and CH0 is not displayed. If possible, could you please modify the attached vi program? Thank you. 2) In the measurement file part, the results of CH0 and CH1 are written vertically, so I would like to write the results of CH0 and CH1 horizontally in parallel. I think this is a basic part, but I'm a beginner, so I apologize.
