Abstract
Embodiments of application relate to the field of communications technologies, and in particular, to a detection apparatus and method for quickly locating a wire fault of a serial bus and finding a cause. The apparatus is connected to a serial bus between a primary device and a secondary device, the serial bus includes a first bus and a second bus, and the apparatus includes a voltage divider module, a voltage follower module, a forward bias module, and a control module that are sequentially connected. The voltage divider module is configured to reduce a voltage of the first bus and a voltage of the second bus. The voltage follower module is configured to enhance an electrical signal of the first bus and an electrical signal of the second bus. The forward bias module is configured to forward bias the voltage of the first bus and the voltage of the second bus.
