CALIBRATION
The ADIS16488A factory calibration produces correction
formulasforthe gyroscopes,accelerometers,magnetometers, and
barometers, and then programs theminto the flash memory.In
addition, there are a seriesof user configurablecalibration
registers for in-systemtuning.
GYROSCOPES
The user calibration for the gyroscopesincludes registersfor
adjusting bias and sensitivity, as shown in Figure 22.

Manual Bias Correction
The xG_BIAS_HIGH registers(see Table65, Table 66, and
Table 67)and xG_BIAS_LOWregisters (see Table68, Table69,
and Table 70)providea bias adjustment function for the output
of each gyroscopesensor.

Bias Null Command
The continuous bias estimator (CBE)accumulates and
averages data in a 64-sample FIFO. The average time (tA)
for the bias estimates reliesonthesampletimebasesetting in
NULL_CNFG[3:0](seeTable 71). Usingthebias null commandin
GLOB_CMD[0](see Table 115), load the correction factors of the
CBEinto the gyroscopeoffset correction registers (seeTable65,
Table 66, Table67, Table68, Table69, andTable70). On/off
controls for the sensors, provided by NULL_CNFG[13:8],
update when issuing a bias null command.Thefactorydefault
configuration forNULL_CNFG enables the biasnull command
for the gyroscopes, disables thebiasnull command forthe accel-
erometers, and establishes the averagetime to ~26.64 seconds.

Turn to Page 3 (DIN = 0x8003) and set GLOB_CMD[0]= 1
(DIN = 0x8201, then DIN = 0x8300)to update the user offset
registers with the correctionfactorsoftheCBE. Ensurethatthe
inertial platformis stableduring the entireaveragetimefor optimal
bias estimates.
