A single six-port automated network analyzer (SPANA) is developed built and tested over UHF, L and S band. The SPANA includes a six-port junction operated as two differential channels receiver, and a test set which comprises a network of switches and directional couplers. By comparison to previous developed six-port based network analyzers, the SPANA uses only one single six-port junction and can perform simultaneous power and S parameter measurements with adjusted test-port impedances.
