Abstract

A PCIE signal measuring circuit is used for measuring a PCIE signal of a PCIE interface board, and the PCIE interface board includes a PCIE signal pin for outputting the PCIE signal. The PCIE signal measurement circuit includes a transfer module and a measurement module, one end of the transfer module is electrically connected to the PCIE interface board, and the other end of the transfer module is electrically connected to the measurement module, so The measurement module is used to obtain and measure the PCIE signal of the PCIE signal pin through the adapter module. The above-mentioned PCIE signal measurement circuit leads out the PCIE signal by setting an adapter module, so as to facilitate testing of the PCIE signal.

Description

technical field [0001] The invention relates to the technical field of signal testing, in particular to a PCIE signal measurement circuit. Background technique [0002] PCI-Express is a high-speed serial computer expansion bus standard. The interface of PCI Express varies according to the bus bit width, including X1, X4, X8 and X16 and so on. The PCI Express specification connects from 1 lane to 32 lanes, and has very strong scalability to meet the different needs of different system devices for data transmission bandwidth. [0003] In order to ensure that the external PCIE device can work stably and efficiently, the quality of the PCIE signal must conform to the PCIE protocol specification. However, in the existing test, the environment collocation and the test process for the quality test of the PCIE signal are relatively complicated, which consumes a lot of time and manpower. SUMMARY OF THE INVENTION [0004] In view of the above, it is necessary to provide a PCIE sig...
