PCIE signal test fixture and data path gating test system thereof

Abstract

The invention discloses a data path gating test system, and the system comprises a golden finger used for being matched with a PCIE slot to be tested in an inserted mode so as to lead out a differential signal of the PCIE slot to be tested, a P-type line gating module which is in signal connection with the golden finger and used for selecting one of DP data paths in the differential signal to be conducted, an N-type line gating module which is in signal connection with the golden finger and is used for selecting one of the N-type line gating modules to be conducted with each DN data path in the differential signal, a gating switching module which is in signal connection with the P-type line gating module and the N-type line gating module and is used for synchronously controlling gating lines of the P-type line gating module and the N-type line gating module; and a joint pair which is connected with the output ends of the P-type circuit gating module and the N-type circuit gating moduleand is used for respectively outputting the differential signals to the signal tester. According to the invention, all data paths of the PCIE signal can be conveniently and quickly tested, the test operation steps are simplified, and the wear of the signal connector is reduced. The invention also discloses a PCIE signal test fixture, and the beneficial effects of the PCIE signal test fixture areas described above.

Description

technical field [0001] The invention relates to the technical field of signal testing, in particular to a data path gating testing system. The invention also relates to a PCIE signal test fixture. Background technique [0002] With the rapid development of the information age, companies and even society need servers to support the storage of more and more data information, which also prompts the design and production of servers. Social development has a sharp increase in information and storage requirements, and servers have gradually penetrated into various fields of society. Information plays an important role as a communication bridge in our daily life. With the rapid development of the server industry, there will be many models of servers designed and produced to meet customer needs in a year. If you want to put them into the market after production, testing the indicators and functions of the server is the key. step. [0003] However, there is still room for develop...

Problems solved by technology

Taking the test of PCIEX8 signal as an example, because PCIE is a differential signal, each Lane has two RF cables, therefore, to complete an X8 test, it is necessary to perform 16 RF cable plugging and unplugging operations, and power-off operations are required when plugging and unplugging. It takes a lot of time to restart the board, frequent plugging and unplugging, and the connector is easily damaged
