An apparatus for converting a two-port vector network analyzer to an N-port vector network analyzer and for calibrating the N-port vector network analyzer includes a test set having a first port coupled to a first port of the two-port vector network analyzer, a second port coupled to a second port of the two-port vector network analyzer and N-ports. The test set includes a circuit that selectively couples one of the N-ports of the test set to the second port of the test set. The apparatus also includes a multi-state transfer standard having N-ports coupled, respectively, to the N-ports of the test set. The multi-state transfer standard provides, at each of the N-ports of the multi-state transfer standard, a plurality of conditions necessary to calibrate the two-port vector network analyzer.
