Abstract

The invention discloses a differential signal detection device which is used for detecting a differential signal transmission line, and two opposite sides of the differential signal transmission lineare respectively provided with a first port to a fourth port and a fifth port to an eighth port. The differential signal detection device comprises a first loop, a second loop, a first comparison circuit, a second comparison circuit and an arithmetic unit. The first loop is used for being electrically connected with the first port and the second port, and the second loop is used for being electrically connected with the third port and the fourth port. The first input end and the second input end of the first comparison circuit are used for being connected with a power end, the first sensing end of the first comparison circuit is electrically connected with the first input end and used for being connected with a fifth port, and the second sensing end is used for being connected with a sixthport. The third input end and the fourth input end of the second comparison circuit are used for being connected with a power end, the third sensing end is electrically connected with the third inputend and used for being connected with a seventh port, and the fourth sensing end is used for being connected with an eighth port. The input side of the arithmetic unit is electrically connected to the first output end and the second output end.

Description

technical field [0001] The invention relates to a detection device for a computer transmission line, in particular to a detection device for a PCI-E transmission line. Background technique [0002] A PCI-E cable is a current bus transmission line, which is used to connect between a computer host and peripheral devices to transmit data, or to connect different computer hosts to transmit data. PCI-E cables include PCIe signal ports, USB signal ports, PHY signal ports, SMBus signal ports, Prsnt signal ports, and P3V3 power signal ports. When it is not normal, it will make the function of the above-mentioned function signal port go wrong. [0003] At present, testing the PCIe signal and SMBus signal in the PCI-E cable is achieved through the Himalia hotplug (hotplug) / Each Card. However, there is currently no suitable test fixture for testing USB signals, PHY signals and P3V3 power signals. [0004] In view of this, in practice, there is indeed a need for an improved bus trans...
