order analysis

[Cap19]

Hi!

I was trying some examples provided by the NI Tool kit, but It is not giving me the correct result.

For Example: If my speed is 6000 rpm then my first order frequency will be 100 Hz, according to which in the order analysis it is giving me a peak. But now if I change the frequency from 100 to say 100.5, then also it is giving me a peak as first order while now the peak is something else than the first order. Can anyone tell me the probable solution?

In order to better understand what is going on, can you please specify which toolkit you are using?  Also, can you please post the inputs and outputs that you are providing to the code and explain what the differences are between what you are seeing and what you are expecting?  Finally, if you have a screenshot of your code, that would be a very helpful addition to your reply posting.

Thanks,
