Abstract
The invention concerns a method for generating calibration signals for calibrating spatially remote signal branches of antenna systems. In accordance with the invention, a base signal is generated by mean of a timer and is fed to a distributor unit for distribution of the base signal to amplifier circuits on the signal distribution lines respectively allocated to them. At the output of the amplifier circuits, a calibration signal is generated respectively via amplification of the base signal within a specifiable upper amplitude limit and a specifiable lower amplitude limit, which is fed to the respective feed-in point of the signal branch to be calibrated that is allocated to an amplifier circuit.
