What is happening on vibration data output in time-domain if the low pass filter (LPF2) of iis3dwb was set to 1333 Hz? Does the vibration data output in time-domain cannot show any vibration data of 6.3 kHz frequency? Please advise. Thanks!

Hi @JTam.1 ,
basically yes, you will get only very attenuated signal above 1333 Hz.
In particular, you can see the amount of attenuation by checking the violet curve in datasheet, p.20:
This mean that a 6.3kHz signal will be attenuated of 20dB. You'll probably see a little signal if the mechanical input event is intense.
