Abstract:
A multi-port device analysis apparatus for testing a multi-port device having three or more terminals, comprising:a network analyzer which sends a test signal from one port and receives an output signal at other port for analyzing the characteristic of a multi-port device under test by vector values; and a multi-port test set connected to the ports of the network analyzer for converting the ports of the network analyzer to three or more ports by a switch provided therein; wherein the multi-port device under test is directly connected to the multi-port test set and data showing the characteristics of the multi-port device is analyzed in vector values; and wherein vector data of the characteristic at each terminal of the multi-port device under test is obtained and the vector data at each terminal is converted to data which corresponds to an optional impedance value to analyze the multi-port device under test.
