The measurement results of the ADXL357 is not smooth. The captured signal is attached.  The test is with ODR=4K, SPI=4MHz, and no high-pass filter.  The signals of each axis are changed like step by step not continuously.


In addition, the measurement results of none moving state are with large noise. The snapshot of the signals is also attached.


I would like to know that both of above cases are correct?
