What is the bias in-run stability / instability of the LSM6DSR gyros and accelerometers?

Hi @WJohn.1​ ,

Since these two AVAR parameters (the bias stability and bias instability) are not tested at production level, I can share you some characterization results on a limited set of data:

• Accelerometer, Velocity random walk (Bias stability)

• Accelerometer, Bias instability

• Gyroscope, Angle walk (Bias stability)

• Gyroscope, Bias instability

Thank you for sharing this.

Any chance you have gyro vibration rejection data for this part?

Hi @Singh.Harjit​ ,

Can you please specify your application?

I can only share you the LSM6DSR Gyro drift related to the below Sinusoidal wave input test on shaker. Gyro ODR is 208Hz.

• Amplitude: 4 g
• Frequency: 100 Hz

The number of tested devices is 22.

Please let me know if these info can help you.

Thank you for sharing. This actually looks really good.

The application is robotics / drone. I'd love to see this over a larger frequency range but I understand you all may not be setup for it.

Hi @Singh.Harjit​ ,

thank you for the appreciation.

Unfortunately I have only these data for ODR 208Hz (and frequency stimulus of 100Hz)... but should be ok at least up to ODR doubled.
