摘要： A device tests the function of an antenna system which includes antenna units each having an antenna and a resistor and is connected between an input of a selection unit and an output of a further selection unit. A computing unit provides a control signal for the two selection units at a first output. The control signal determines which input is connected to an output of the selection unit, and which of the outputs of a further selection unit is supplied with a bias voltage present at the input of the further selection unit, and to receive the antenna signal present at the output of the selection unit at an input of the computing unit. A diagnosis circuit is connected between the output of the selection unit and a diagnosis voltage terminal. The computing unit infers a fault in the antenna system from the comparison of antenna signals.

摘要： A device tests the function of an antenna system. The antenna system has a plurality of antennas that are interconnected with an assigned input of a selection unit. The antennas of a first antenna group are interconnected with the inputs of a first multiplexer. The antennas of a second antenna group are interconnected with the inputs of a second multiplexer. The antennas of the first and second antenna groups are arranged adjacently and/or overlap in pairs. A computing unit provides control signals for the selection unit to feed an AC signal into a selected antenna of the first antenna group and to capture the antenna signal present on each antenna of the second antenna group for the selected antenna at an output of the selection unit. A fault is inferred from the comparison of the determined antenna signals for the selected antenna and associated expected antenna signals.
