Problems solved by technology

Prior art is to carry out power full-load test with the graphics card, network card etc. that conform to PCI Express specification as test card, but because the power of these products such as graphics card, network card is preset, and PCI Express has multiple interface specifications, each The maximum rated power of the interface specification is different, so in the actual test process, the PCI Express interface cannot achieve the real full load test, resulting in inaccurate testing; and to test different PCI Express interfaces, different PCI Express test cards need to be inserted. Inconvenience for testing

Abstract

The invention comprises: a PCB fitting the relevant interface specifications and a load simulation device comprising a voltage stabilizer used for tuning the output voltage and a load unit used for receiving the output voltage and consuming the power. It can be used for testing the maximum required power of interface awaiting test by using said load simulation device.

Description

technical field [0001] The invention relates to a test card, in particular to an interface power consumption test card. Background technique [0002] In the development process of electronic systems, reliability testing is an important hurdle to ensure product quality, one of which is the power full load test of the system interface. The following uses the PCI Express interface as an example. [0003] PCI Express is a new generation bus interface. In 2001, Intel Corporation proposed to use a new generation of technology to replace the PCI bus and the internal connections of various chips, and called it the third-generation I / O bus technology. Then at the end of 2001, more than 20 leading companies in the industry, including Intel, AMD, DELL, and IBM, began to draft the specifications of the new technology, which was completed in 2002 and officially named PCIExpress. [0004] PCI Express adopts the current popular point-to-point serial connection in the industry. Compared ...
