Abstract
According to one embodiment of the invention, there is provided an N-port automatic calibration device comprising N-ports, wherein each port is adapted to be coupled to a port of an N-port multiport test set. The N-port automatic calibration device comprises a single-pole, N−1 throw switch having a single-pole coupled to a first port of the automatic calibration device and having each throw of the N−1 throws coupled to a corresponding port of the automatic calibration device. In addition, the N-port automatic calibration device comprises at least one single-pole, double-throw switch, having a single-pole coupled to a second port of the N-ports of the automatic calibration device, having a first throw coupled to a first load impedance, and having a second throw coupled to a throw of the N−1 throws of the single-pole, N−1 throw switch.
