The invention relates to a communication technique. The invention can be used for solving the problems of a traditional communication device that a hardware testing mode of a synchronous asynchronous serial interface is inferior in intuitive performance, a fault is difficult to be positioned and the quality of products is difficult to be ensured because detection is not comprehensive enough. The invention provides a hardware testing device and method for a synchronous asynchronous serial interface. The technical scheme is as follows: the hardware testing device for the synchronous asynchronous serial interface is connected to the synchronous asynchronous serial interface of a tested device through a first synchronous asynchronous serial interface; a second synchronous asynchronous serial interface is respectively connected to the first synchronous asynchronous serial interface and a synchronous asynchronous serial interface test connector having a loopback; and a signal detection circuit is respectively connected to the first synchronous asynchronous serial interface and a state display module. The hardware testing device provided by the invention has the beneficial effects that the level, quality, stability and amplitude of each signal are directly reflected and the hardware testing device is suitable for the hardware test of the synchronous asynchronous serial interface.
