I am using BMG250 MEMS gyroscope. I am observing a "Sinusoidal Noise" of primary frequency approximately 8 Hz in a few samples of the sensors. I have attached the plots for the reference. I am not able to decode the reason behind the same. This is also reflecting in the Allan plot and seriously affecting the ARW values. I request you to please suggest any solution for the same. Data points were recorded at the non-vibrating platform with variable sampling rates (50 Hz, 400 Hz). Used different power sources (Dedicated Power Supply, Adaptor, independent battery).
