Test device and method of high-speed video bus connectors

The invention discloses a test device and method of high-speed video bus connectors. The test device comprises a test main board provided with connectors to be tested and auxiliary boards provided with connectors to be tested, and test ports connected with a test instrument are arranged on the auxiliary boards. The test method comprises the steps that electromagnetic simulation software is called in a PCB layout file of a de-embedding structure to carry out simulation so that electromagnetic parameters of the de-embedding structure can be obtained; a network analyzer is used for testing the test device, and carrying out de-embedding operation on an obtained test result and the electromagnetic parameters, obtained through simulation, of the de-embedding structure, and connector electromagnetic parameters are obtained; the test device is powered up, an error detector is used for carrying out error code tests, and the error rate of the connectors is obtained. The test device and method of the high-speed video bus connectors are complete in test content of the high-speed video bus connectors, the electrical parameters are fully tested, test parameters are accurate, and the test device and method are wide in application range.
