Two-port network theory provides the theoretical basis for making network measurements. Two-port network theory can be expanded to N-port theory for networks having more than two ports while one-port measurements are essentially a subset of two-port measurements. The simplest of two-port measurements is the gain or transfer function of the device. This assumes a fairly simple model of the device under test. More complete two-port models such as impedance parameters provide a better view of device behavior, while scattering parameters present a twoport model which is consistent with transmission line theory and measurements.
