I use IIS3DWB vibration sensor. I set maximum bandwidth 6.3 kHz and FFT size 2048. What acquisition time should I use when using MotionSP library?

Hi @JTam.1 ,
I would say that you need at least 2x6.3 ksamples to respect Nyquist, , so with an ODR of 26.667 kHz you would need half a second per acquisition.

Hi @JTam.1 ,
what ODR are you working with?
