Table 1. Error in Soft Iron Correction Factors [er001]
Background
Issue
Workaround
Related Issues The signal chain for the tri-axis magnetometer in the ADIS16488A includes a user-configurable, 3 × 3 soft iron correction
matrix. Users configure each value in the soft iron correction matrix by writing to its corresponding register. For example,
the SOFT_IRON_S12 register contains the value for correction factor S12. In these registers, 1 LSB = 100/215.
On units that have firmware Revision 1.07 (or earlier), 1 LSB = 12.5/215, which is eight times lower than the correct value,
on the following registers: SOFT_IRON_S12, SOFT_IRON_S13, SOFT_IRON_S21, SOFT_IRON_S31, and SOFT_IRON_S32.
Read FIRM_REV to determine the firmware revision of a unit. If FIRM_REV < 0x0108, clear all soft iron correction values
(write 0x0000 to each SOFT_IRON_Sxy register) and perform the soft iron correction outside of the ADIS16488A.
None. Table 2. User Offset Addition Error [er002]
Background
The ADIS16488A provides user-configurable bias correction values for each gyroscope and accelerometer(x, y, and z),
through the following registers: XG_BIAS_HIGH, XG_BIAS_LOW, YG_BIAS_HIGH, YG_BIAS_LOW, ZG_BIAS_HIGH,
