Abstract

A network analyzer includes an n-port network with two ports for measuring wave parameters of a measurement object. Each port has a feed for a radio-frequency signal from a signal source. Signal components of the radio-frequency signal fed into the respective port are reflected at the measurement object and the signal components of one or more radio-frequency signals fed into at least one other port are transmitted through the measurement object to the respective port are measured as wave parameters. The two ports are supplied with different radio-frequency signals, wherein frequencies or frequency bands are offset with respect to one another by a frequency offset. Reflected and transmitted signal components of the radio-frequency signals are measured at the same time at the two ports.
