In many applications it is necessary to make multiport measurements. The RNVNA links up to 16 1-Port analyzers together into a multiport network analysis system. Each of the 16 analyzers will make individual vector reflection measurements and scalar transmission measurements from port to port. In other words, S11, S22, S33 and so on will be complex measurements and S21, S31, S41 and so on will be scalar only measurements.
