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.

Calibrating non-linear data

An example system includes capture circuitry to obtain first parametric data based on a first signal at an interface to a first communication channel, with the first parametric data representing non-informational content of the first signal; and control circuitry to receive the first parametric data and to provide second parametric data, the second parametric data being based on one or both of: the first parametric data or a programmatic input. The example system also includes interface circuitry to receive the second parametric data and to receive informational content data representing informational content, and to process the informational content data and the second parametric data to produce a second signal. The second signal has the informational content represented by the informational content data and having at least some non-informational content based on the second parametric data.

Parametric information control

An example system includes circuitry to receive an input signal, to provide a related signal based on informational content of the input signal, and to obtain parametric data associated with the input signal. The parametric data represents one or more signal characteristics other than the informational content. The example system also includes a first switch that is configurable to provide first data based on the related signal to one or more first channels of the system; and a second switch that is configurable to provide second data based on the parametric data to one or more second channels of the system.
