Abstract
In a method for measuring transmission parameters of a balanced pair, a unbalanced type equipment which is widely used as compared to a balanced type equipment which is not used in practical is used. In the measurement, the balanced pair is connected to the unbalanced type equipment or via a unbalanced/balanced type transformer thereto at the measuring end, wherein predetermined terminated states are set at the measuring and far-ends to measure input admittances dependent on the terminated states. A characteristic impedance and a propagation constant for the transmission parameters are calculated from predetermined equations into which the measured input admittances are substituted.
