ABSTRACT:
A network analysis system and methods facilitate a match-corrected signal power measurement using a vector network analyzer (VNA). The network analysis system includes the VNA and a computer program stored in memory and executed by a controller. The computer program has instructions that implement one or both of calibrating a test port of the VNA to determine the match-corrected signal power measurement and correcting a power measured for a signal received at the test port of the VNA using corrected error terms of a port calibration of the test port to yield a corrected measured power. The corrected error terms are determined from error terms of the port calibration using a switch term and an incident power calibration, both of the test port. A method100determines the match-corrected signal power measurement and a method300calibrates the VNA test port to determine the measurement.
