We have run a test scenario for our new design product which includes ADIS16475-2. When we observe test results there is a problem shown in figures clearly.
1) TEST INFORMATION
IMU: ADIS16475-2
Firmware Rev : 0x0134
Month Day : 0x0325
Year : 0x2023
Serial : 0x1369
IMU Sample Rate: 1000 Hz
2) VIBRATION PROFILE
IMU is placed on circuitboard and has metal enclosure. The complete enclosure is placed on
vibration table. Frequency Range: 10-2000 Hz and 1,3 and 5 grms vibration tests are realised
without a mechanical isolator. The test table is vibrated in Z axis. IMU body axes and test table’s
axes are aligned.
3) TEST DATA
It is observed that, after the vibration occured, accelerometer data (all 3 axes) has considerable
errornous bias shifts. Only the Z axis acceleration data is shared below however the other axes
have the same characteristics. After each vibration test, it is expected that accelerometer
measures zero acceleration in X and Y axes and 1 g in Z axis.
