When using ChirpZ transform of LabVIEW(The example itself provides),I found a strange thing.When the frequency is very big and the range is small together with a not small number of ChirpZ transform,Error happened(very bad spectrum and wrong frequency ChirpZ's result is)! Nothing is wrong with the examples(I've scripted other VIs to verify this),and this error didn't happend using MATLAB. So I believe that is a bug of LabVIEW!!!(Not Sure yet of course). I Need Help! Talent Masters, Come out!

You should post in the correct forum topic. This is for providing code that others can use, not for asking questions about (possible) errors.

Topic moved.

 

Also have you contacted NI about this?  If this is a real problem they will want to make a CAR for it so it can be fixed.
