Embodiment Construction
[0026] The principle and spirit of the present disclosure will be described below with reference to several exemplary embodiments. It should be understood that these embodiments are given only to enable those skilled in the art to better understand and implement the present disclosure, rather than to limit the scope of the present disclosure in any way. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
[0027] figure 1 is an exemplary schematic diagram illustrating transmission of differential signals by a DP cable. Such as figure 1 As shown in , the display port (DisplayPort, “DP”) cable 100 may include two connectors 101 , and an electronic device (not shown in the figure) is disposed in each connector 101 . Further, the two connectors 101 are connected through a copper wire or an optical cable, so as to realize, for example, data signal (eg, audio s...

The invention relates to a device for detecting a high-speed differential signal and a method thereof. The device comprises a signal generator, a signal receiver, an error code calculation unit which is used for comparing the high-speed differential signal sent by the signal generator with the high-speed differential signal received by the signal receiver so as to obtain an error code in the high-speed differential signal received by the signal receiver and according to the error code in the high-speed differential signal received by the signal receiver, determining whether the P / N end of the high-speed differential signal is in an open circuit or short circuit state, and an eye pattern calculation unit which s used for generating a two-dimensional eye pattern according to the high-speed differential signal received by the signal receiver, performing statistics on the first error code rate of the corresponding area in the two-dimensional eye pattern, and determining whether only one path of the high-speed differential signal P / N end is in an open circuit or short circuit state according to the statistical result. By using the scheme of the invention, the short circuit or open circuit condition of the high-speed differential signal can be effectively detected so as to accurately judge the quality problem of the cable.
Description
technical field [0001] The present disclosure generally relates to the field of cable technology. More specifically, the present disclosure relates to a device, a method, a transmission cable device, and a computer-readable storage medium for detecting high-speed differential signals. Background technique [0002] Differential transmission is a signal transmission technology, which is different from the traditional transmission mode of one signal line and one ground line. The aforementioned differential transmission is to transmit signals on the two lines, and the transmitted signals on the two lines are differential signals, and the differential signals have the same amplitude and opposite phases. In the application scenario, the signal receiving end usually compares the difference of the differential signal voltage to judge the logic state sent by the sending end. It can be appreciated that the differential signal can control the "reference" voltage, so that small signal...
