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 uTest, having a carrier frequency f1 and a digital signal uCode modulated thereon; generating a second HF signal u2 having a frequency f2; introducing the first HF signal uTest and the second HF signal u2 into 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 uRX; recovering a digital signal udemod from uRX; and determining a time shift tx between the digital signal uCode and the recovered digital signal udemod. The invention further relates to a measuring device for performing this method.
