In microwave circuit design S-parameters are very useful for the full characterisation of any 2 port Network. In contrast to z,y and h-parameters, which require broadband short circuited and open circuited connections at the TEST ITEM for the measurement, S-parameters are determined with input and output terminated with the resistive characteristic impedance of test systems (generally 50 ohms in a coaxial line system). Parasitic oscillations in active devices are minimised when these devices are terminated in resistive loads. S-parameters are complex, having a magnitude and a phase relationship, and are measured in terms of incident and reflected voltages using a VECTOR VOLTMETER or VECTOR NETWORK ANALYSER (VNA).
