Hello, I am a LabVIEW beginner. I need to create a multitone using LabVIEW, and I also need to be able to adjust the number of tones. I have tried two approaches: using the "multitone generator.vi" or the "basic multitone generator.vi".
When I used the "multitone generator.vi" (filename: "makingcomb.vi"), I was able to see the multitone on LabVIEW's spectrum form. I could also add amplitude and phase to each array in the fundamental frequency to add more tones. However, when I tried to view the tones using my spectrum analyzer and N200, I couldn't see them. The spectrum analyzer only reacted to the carrier frequency. However, I am aware that multitone is not related to the carrier frequency.
When I used the "basic multitone generator", I still couldn't see the tones using my spectrum analyzer.
