Abstract
A method for measuring intermodulation produced in a measurement segment of a signal transmission path, by: producing a first HF signal (u(t)) and a second HF signal (u(t)), both having a predetermined frequency progression; feeding the first HF signal (u(t)) and the second HF signal (u(t)) to the signal transmission path, wherein an intermodulation signal is produced, which intermodulation signal has a first intermodulation signal component (u(t)) produced in an input segment of the signal transmission path and a second intermodulation signal component (u(t)) produced in the measurement segment of the signal transmission path; producing a compensation signal (u(t)) in accordance with the first intermodulation signal component (u(t)) produced in the input segment; introducing the compensation signal (u(t)) into the signal transmission path in order to reduce or cancel out the first intermodulation signal component (u(t)). The invention further relates to a measuring device for performing said method.
