Abstract

A system for VGA port testing comprises an oscilloscope connected with a VGA port of a tested mainboard. The oscilloscope is used for testing signals output by the VGA port, the system for VGA port testing further comprises a testing machine table, and the testing machine table is connected with the oscilloscope and used for automatically adjusting parameters of the oscilloscope and automatically generating test reports according to the waveform tested by the oscilloscope and displaying test results. The invention further discloses a testing method based on the system for VGA port testing. The system and method for VGA port testing are high in automation degree, and test results are accurate.

Description

technical field [0001] The invention relates to a VGA port testing system and method. Background technique [0002] All existing computer hosts have a VGA (Video Graphic Array, display graphics array) port for outputting video signals. When testing the VGA port, a monitor is usually connected to the VGA port, and the VGA port outputs video signals to the monitor for display, and then manually observe whether the image displayed on the monitor is normal. However, the traditional VGA port testing method is not highly automated, and the test results are not accurate. Contents of the invention [0003] In view of the above, it is necessary to provide a VGA port automatic test system and method with relatively accurate test results. [0004] A VGA port test system, comprising an oscilloscope connected to the VGA port of the tested motherboard, the oscilloscope is used to measure the signal output by the VGA port, the VGA port test system also includes a test machine, the The...
