Linearizer Input

Piece-wise approximation is the method used to linearize the signal, i.e., the linearizer’s output to input relationship can be graphed as a number of straight line segments connected together to approximate the desired curve that would be required to compensate for the nonlinearity of the bench

The points at which the compensation curve changes slope are called breakpoints. The slope of each segment corresponds to the gain of the linearizer in that segment, and this gain has to vary according to the input voltage. This is achieved through software by adjusting a multiplier factor at each straight line segment. The linearizer has nine specific voltage segments.
