METHOD AND MEASURING DEVICE FOR INTERMODULATION MEASUREMENT

摘要

The invention relates to a method for intermodulation measurement, in particular for locating points in a signal transmission path for a high-frequency signal that are faulty with regard to high-frequency transmission properties of the signal transmission path, comprising the following steps: generating a first HF signal uTest, which has 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, in the form of an intermodulation product signal uRX; recovering a digital signal udemod from the intermodulation product signal; 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 said method.
