Abstract
A calibration standard (204) provides interconnection between measurement ports (212, 214, 216) of a network analyzer (202) having at least three measurement ports. Once the measurement ports (212, 214, 216) of the network analyzer (202) are interconnected, a non-zero signal transfer is generated between each of the measurement ports and at least one other measurement port as part of the calibration process. Interconnecting all of the measurement ports (212, 214, 216) together and generating non-zero signal transfers characterizes the relative relationship between the ports during the calibration process. The calibration standard (204) can also provide a desired level of mode conversion.
