Problems solved by technology
Although the above method can quickly detect the connection status of each module on the middle board, with the advancement of technology, people's demand for high-speed data processing is increasing day by day, but the existing online test method cannot effectively detect the high-speed signal transmission of the middle board. Whether there is a problem of poor contact when passing
In addition, the existing online test environment cannot generate high-speed signals (such as 8Gbps signals applied to PCI-E3.0), so that it is impossible to verify the pin contact conditions of the system during high-speed operation
[0003] In practical applications, once the contact condition of the pins is poor, the overall device will not be able to achieve the best performance

The invention discloses a signal detection device and method. The signal detection device comprises a signal generation unit, a situation simulation unit and an analysis unit. The signal generation unit is used for outputting test signals; the situation simulation unit comprises a situation simulation card to simulate modules of an electronic system, and the situation simulation unit receives the test signals to output corresponding feedback signals; the analysis unit receives the feedback signals to judge the connection state of module pins of the electronic system. A tester can effectively test whether signal transmission of the electronic system is abnormal or not under high-speed operation and whether the pins make bad contact or not.
Description
technical field [0001] The present invention relates to a signal detection technology, in particular to a signal detection device and method. Background technique [0002] In the prior art, an In-Circuit Test (ICT) method is used to test whether the pins on each module are connected by thimbles for the test of the middle board. Although the above method can quickly detect the connection status of each module on the middle board, with the advancement of technology, people's demand for high-speed data processing is increasing day by day, but the existing online test method cannot effectively detect the high-speed signal transmission of the middle board. Whether there is a problem of poor contact when passing. In addition, the existing in-circuit test environment cannot generate high-speed signals (such as 8Gbps signals applied to PCI-E3.0), so that it is impossible to verify the pin contact condition of the system during high-speed operation. [0003] In practical applicatio...
