  • Power calibration for multi-port vector network analyzer (VNA)
    Patent number: 7061254
    Abstract: A power calibration method for a multi-port vector network analyzer (VNA) performs a two-port S-parameter calibration between a pair of ports of the multi-port VNA, and performs a power calibration of one of the ports in the pair of ports. From the two-port S-parameter calibration and the power calibration at the one port, power can be determined at one or more ports of a device under test (DUT) coupled to the ports of the multi-port VNA.
