Hello,
We are using the ASM330LHH in a design and are seeing extremely large gyro biases (~250 deg/s). I am trying to figure out what may be causing them; here is some information on the experiment. We collect data while spinning our custom boards (with an ASM330LHH mounted on them) at various rates from 0-800 deg/s on a rate table so that we can calibrate the IMUs. Below I have attached two images of the data collected at the same time (using the same software) from two different ASM330LHH units. Note that in this particular collect, the devices are positioned so that the y axis is aligned with the axis of rotation, but these biases stay regardless of the orientation relative to the axis of rotation. Any ideas what could be causing such a large bias?
Unit 1 (exactly as I would expect the data to look)
Unit 2 (apparent bias of 255 dps in the x axis and -130 dps in the z axis)
