Gain Matching
Gain matching is a figure of merit that indicates how
well the gains between the two channels are matched
to each other. The same input signal is applied to both
channels and the maximum deviation in gain is report-
ed (typically in dB) as gain matching.
Offset Matching
Like gain matching, offset matching is a figure of merit
that indicates how well the offsets between the two chan-
nels are matched to each other. The same input signal is
applied to both channels and the maximum deviation in
offset is reported (typically in %FSR) as offset matching.
