In the follow ing exam ple, analog gain is set for all taps. The peak valu e of each tap w ithin
the region of interest is calibrated to the specified target valu e. All taps com pletely
ou tsid e the region of interest are calibrated to the average analog gain valu e of the taps
insid e the region of interest.

W hen calibrating all taps , taps com pletely outs ide the region
of interes t (in this exam ple, taps 1to 4 and 14 to 16) are calibrated to the
average analog gain of taps within the region of interes t. T aps
within the region of interes t calibrate to the target value. Note: S eam s
between taps will be vis ible until you perform P R NU calculation us ing
the ccp com m and.
Sets the analog offset. The analog offset should be set so that it is
at least 3 tim es the rm s noise value at the current gain. The analog
offset is configured for noise at the m axim um specified gain and
as a result you should not need to ad just the analog offset.
