Zusammenfassung:PROBLEM TO BE SOLVED: To provide a means that is not more complex and accurately calibrates a vector network analyzer. SOLUTION: In one embodiment, a method comprises applying a stimulus signal to a reference frequency translation device (FTD) 108 by a vector network analyzer 500 during a calibration mode, wherein the reference FTD possesses equal conversion efficiency in forward and reverse directions and the reference FTD possesses unknown input and output reflection characteristics; measuring a response of the reference FTD; and determining forward and reverse transmission tracking error terms 505 using data from the measured response and single-port error calibration terms.
