Abstract
A method for intermodulation measurement for locating points in a signal transmission path for a high-frequency signal that are faulty with regard to HF transmission properties of the signal transmission path, by generating a first HF signal u, having a carrier frequency fand a digital signal umodulated thereon; generating a second HF signal uhaving a frequency f; introducing the first HF signal uand the second HF signal uinto the signal transmission path at a predetermined introduction point; receiving an intermodulation product, which is generated in the signal transmission path from the first HF signal and the second HF signal at at least one faulty point, as an intermodulation product signal u; recovering a digital signal ufrom u; and determining a time shift tbetween the digital signal uand the recovered digital signal u. The invention further relates to a measuring device for performing this method.
