Abstract

A method and a device for directly digitizing microwave signals reflected on a filling product surface of a filling product present in a receptacle, wherein the microwave signals reflected on the filling product surface are scanned, and the analog values resulting from said scanning process are stored in an analog value storage means. The stored analog values are then read out from the analog value storage means at a lower rate as compared to the scanning rate, and are converted into digital values. The digital values may then be made available to an evaluation means for determining the filling level height.
