ABSTRACT:
A method is provided for switching between two oscillator signals within an alignment element. In accordance with the method, one of the two oscillator signals one is selected as a first master signal in order to provide an output stepping signal at an output of the alignment element. The method comprises introducing a virtual stepping signal when a switch between the two oscillator signals occurs or when a failure in the first master signal is detected. The method further comprises sending the virtual stepping signal to the output of the alignment element in the event of a switch until an alignment with a new master signal is completed.
