I set up two experiments for BMI088 as follows to analyze a relationship between the sensitivity drift error and the operating temperature.
#1 experiment
1. Let the IMU be cool to -40°C in a cooling chamber.
2. Record the IMU data on a rate table at 300dps in the ambient environment until the operating temperature reaches 70°C.
#2 experiment
1. Test the IMU on a rate table at 300dps in the ambient environment.
2. Keep recording the data while cooling down the IMU.
The figure below shows the comparison. I was expecting two experiments would give me the same result, but obviously, the rate is slightly lower in #2. Since I do not see related data in the datasheet, I have no idea If this what I could expect. Is there any related experiment being done on your side so that I can compare mine with it?
Thanks!
