Abstract
A method for vector characterization of a frequency translation device (“FTD”) includes coupling a first signal from a first signal source through a reference directional coupler and through a test directional coupler of an electronic test set to a first port of the FTD. A second signal from the reference directional coupler is coupled to a first receiver of a vector network analyzer (“VNA”). A third signal is coupled from the test directional coupler to a second receiver of the VNA; and a vector parameter of the first port of the FTD is measured with the VNA.
