Abstract
A vector stimulus/response system enables the vector responses of frequency translation devices (FTDs) to be accurately characterized. The system includes a source, having a predetermined source match, reflection tracking and directivity, that generates a stimulus signal. A receiver having a predetermined load match is also included in the system. The receiver measures a first series of responses of a reference translator to the stimulus signal, when the reference translator is coupled between the source and receiver. The reference translator has predetermined transmission characteristics, input match and output match. The receiver measures a second series of responses of a FTD to the stimulus signal. A processor generates a correction array from the first series of responses, the predetermined transmission characteristics, input match output match, source match, and the directivity, reflection tracking and load match. The processor then applies the generated correction array to modify the second series of responses to provide vector characteristics of the FTD. A phase coherent reference and an amplitude reference for the receiver are provided by a parallel reference path or by a s…
