Wake-up signal test system having a test card for testing wake-up signal output by a platform controller hub of a motherboard

摘要

A wake-up signal test system to test a wake-up signal output by a platform controller hub (PCH) of a motherboard includes a test card and an oscillograph. The test card includes a board with an edge connector, and a button. The button is connected between a first ground pin and a first wake-up signal pin of the edge connector. When the edge connector is inserted into a peripheral component interconnect express (PCIe) socket of the motherboard, the first ground pin is connected to a second ground pin of the PCIe socket, the first wake-up signal pin is connected to a second wake-up pin of the PCIe socket. When the button is pressed, the first wake-up signal pin is connected to the first ground pin to output a low level signal to the PCH to wake up the motherboard. The oscillograph displays a voltage state of the low level signal.
