Hello, I was trying to performe a nonlinear curve fit of a sinusoid that I get from my oscilloscope. I thought it was kind of simple, I looked at some of the examples and I read some related topics on this forum (this is the closest one to my goal in my opinion: http://forums.ni.com/t5/forums/v3_1/forumtopicpage/board-id/170/thread-id/789317/page/1 ) however it did not work.
My goal is basically to reconstruct a sinusoidal curve when the signal is not completely visible in the display (or let's say to calculate my maximum/minimum value and the zero-crossing.
I attach a VI with three versions of the same 10GHz signal, the first one where the signal is completely visible, the second one where it's out of scale in the X axis (not the whole period is visible) and the 3rd one where the Y axis (amplitude) is out of scale.
I hope you can help me! Thanks!
Thank you!
