LSM6DSL Faulty Reading?

Hi,

 

I'm investigating the use of the LSM6DSL in a future project (to replace our use of the LSM6DS3) and I have been testing the STEVAL-MKI178V1 evaluation part.

 

There appears to be some strange signal on the Z axis of the accelerometer (that was not present on the older LSM6DS3), have I just received a faulty part?

 

I've attached pictures of 30s of measurement data from the 6 axes (gyro_x, gyro_y, gyro_z, accel_x, accel_y, accel_z) with the sensor in 3 different orientations. The strength of the rogue signal always seems to be constant (around 100 LSB, or 6 mg at our scale).

 

The sensor is configured to be in high performance mode, 104 Hz output data rate, +-2g full scale.

 

Thanks,

Nick
