1. A method of measuring a multiport device using a multiport test set comprising the steps of:
- connecting one port of the multiport device to a stimulus signal, terminating all remaining ports of the multiport device in a respective dedicated load, measuring a response to the stimulus signal on all ports of the multiport device, and correcting said measured responses with calibration data to characterize the multiport device.

Abstract
A method and apparatus for measuring a multiport device using a multiport test set connects one port of the multiport device to a stimulus signal and terminates all remaining ports in a respective load. A response to a stimulus signal is measured on all ports of the multiport device and the measured responses are corrected with calibration data to characterize the multiport device.
