Abstract:
A method is provided for calibrating a test platform to establish a phase relationship between copies of a signal at a measurement location within the test platform. Phase relationships of the copies of the signal traversing signal paths and ending at the measurement location are manipulated. Vector signal addition from the copies of the signal is analyzed as the phase relationships are manipulated to find a phase offset adjustment that establishes a particular phase relationship between the signal paths.
