Adapter correction in the measurement of two-port devices

After an automatic network analyzer has been calibrated at its primary connectors, the full scattering matrices of adapters can be found with two known reflection standards in the secondary connector system. In coaxial systems, the standards can advantageously be a matched load and two 'half standards'-a short for phase and an open circuit for magnitude. The method is applicable to noninsertable devices, waveguides, and novel transmission lines.<
