Calibrating non-linear data

Abstract:

An example system includes non-transitory machine-readable storage storing calibration data sets. A calibration data set includes parameter values that vary non-linearly. Each of the calibration data sets is temperature-specific. The example system also includes channels over which signals pass to and from units under test (UUTs). A channel includes input circuitry to receive a signal of the signals and to obtain a first parameter based on the signal; and correction circuitry to obtain a second parameter based on the first parameter and based on the calibration data set. The second parameter includes a calibrated version of the first parameter. The calibration data set is selectable based on temperature.
