Abstract

The invention discloses a signal testing system. According to the system, all signals in a to-be-tested MXM interface can be smoothly connected to a connector in a one-to-one correspondence manner through a switching MXM interface and a connecting line, and a signal obtaining device can obtain a to-be-tested PCIe signal outputted by the to-be-tested MXM interface through the connector through theconnection with the connector, so that the signal quality of the PCIe signal to be tested can be tested, the signal quality problem of the PCIe signal can be discovered in time, the signal integrity of a PCIe link of a system to be tested is ensured, and the normal use of a graphics processor is ensured.

Description

technical field [0001] The invention relates to the field of signal testing, in particular to a signal testing system. Background technique [0002] MXM (Mobile PCI-Express Module, dedicated PCIe signal interface for graphics processors) interface is based on PCIe (Peripheral Component Interconnect express, high-speed serial computer expansion bus) interface, a device interface designed for graphics processors, MXM on the motherboard The signal quality of the PCIe signal in the interface may have problems due to various reasons, but there is no mature signal test system in the prior art that can test the signal quality of the PCIe signal in the MXM interface, so that it is impossible to detect the PCIe signal in time. The signal quality problem of the signal affects the normal use of the graphics processor. [0003] Therefore, how to provide a solution to the above technical problems is a problem that those skilled in the art need to solve at present. Contents of the inve...
