a question about ADIS16227


I want to use 16227 to calculate the RMS of speed,However, I found that there is a difference between the external calculation of the fast Fourier transform and the Fourier transform given by the sensor. The waveforms are similar, but the magnitude is different。

  • Hi Ron123,

    Thank you for considering the ADIS16227.  Have you seen the ADcmXL3021 yet? 


    It offers much stronger performance and an expanded set of functional features that make it much more capable than the ADIS16227.  

    With respect to your comment, it seems like you are just offering a statement.  Did you have a question?  If you are looking to compare two different measurements, I suspect that we will need more detail on the "external calculation," especially if you are asking us to presume that this is the "truth measurement."  

    Just for your information, for now.... 

    Thank you,
