Time Domain Analysis with Copper Mountain Technologies Vector Network Analyzers (VNA)

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.

TRL Calibration of a VNA

Thru-Reflect-Line calibration has a number of advantages over the SOLT method often used in VNA calibration. For SOLT calibration, the standards must be accurately characterized. The opens and shorts might be characterized by electromagnetic simulation of the physical design or have associated one-port “data-base” files obtained by highly precise measurement.
