Abstract:
1. A network analyzer, comprising: an n-port device having a first and a second port for measuring wave parameters of a measurement object, a first and a second signal source, wherein the first port has a feed for a first radio-frequency signal from the first signal source, and wherein the second port has a feed for a second radio-frequency signal from the second signal source, wherein a first signal component of the first radio-frequency signal fed in to the first port, which is reflected at the measurement object, and a second signal component of the second radio-frequency signal fed into the second port, which is transmitted by the measurement object to the second port are measured as wave parameters, wherein, during operation of the network analyzer, the two ports of the n-port device are supplied with different radio-frequency signals, wherein frequencies or frequency bands are offset with respect to one another by a frequency offset, and wherein reflected and transmitted signal components of the radio-frequency signals are measured at the same time at the two ports.
