Abstract
A checking apparatus can test at least one first closed-loop control unit. The checking apparatus can include a first timing transmission unit which can generate a first periodic timing signal from a first time signal, and which can output the first periodic timing signal to a first PLL. The check device can further include a first oscillator which can generate a second periodic timing signal and which can output the second periodic timing signal to a second PLL. The checking device can additionally include a first clock, and can forward a first clock signal to a first input/output unit, and/or to a first computation unit. A first changeover signal can be used to control a first multiplexer such that depending on a state of the first changeover signal, the first multiplexer can forward either a first frequency-stabilized timing signal or a second frequency-stabilized timing signal to the first clock.
