Gyroscope Output Noise - BMI088

Hi all,

I am testing BMI088 on a rate table (benchmark) and see how it performs. The following is the plot for the x axis.

The rms of the noise is increasing from 0.4 to 1 deg/sec as the rate goes up. The output density in the datasheet is 0.014 deg/sec/sqrt(Hz) and the BW=32 in my case, so the rms should be around 0.08 deg/sec. This is way smaller than what I got especially when increasing the rate.

Is this normal? If not, what may cause the issue?

 

Thanks!
