Abstract :
The architecture of traditional coaxial systems for highly accurate admittance comparison has been redesigned taking into account the features of active-compensated multi-coaxial connection structures previously developed and investigated. When applied to the conventional two-port transformer bridge, the new approach makes the parasitic cable effects negligible, and allows comparison of four-port standards even in parallel connection.
