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.
