Hi,
BMI088 gyro has typical noise density of 0.014dps/rt(Hz). At 23Hz bandwidth, the RMS noise level (1-sigma) = 0.014 * root(1.22 * 23) = 0.08dps, where 1.22 is the coefficient of internal low pass filter. So 3-sigma RMS noise level = 0.24dps. If you calculate the standard deviation from your data collection Excel file, then you can check if it is within the 3-sigma of 0.24dps range or not. If you see gyro data spikes, then please check if you read 6-byte gyro data registers in one I2C or SPI transaction or not which is also called burst read.
Thanks.
