    HI @SM.4​ , the datasheet values usually refer to the parameter tested in production line

    1. Bias Random Walk Noise standard deviation of Accelerometer & Gyroscope

    I believe you are referring to Angular / Velocity random walk and Bias Instability. In this case, you can find characterization values here below, for both Accelerometer and Gyro

    3. Measurement noise standard deviation of Accelerometer & Gyroscope

    You can find here below some characterization data on N.50 samples
