【摘要】 针对企业生产VGA数据线性能测试方面的需求,设计一款VGA数据线测试仪。该测量仪按照VGA视频流格式把VGA视频流信号通过被测数据线进行传输,然后通过计算其VGA视频流信号的错误率来判断数据线性能的好坏。实验结果和实际应用表明,该仪器较其他测试方法具有测试速度快,测试结果准确等优点,可广泛地应用于VGA数据线生产企业。更多还原

【Abstract】 A VGA data cable tester was designed to satisfy the demand for the performance test of VGA data cable produced by enterprises. With the tester,the VGA video stream signal is transmitted through the tested data line according to the VGA video stream format,and then the error rate of VGA video streaming signal is calculated to determine the performance of data cable. The experimental results and practical application show that,in comparison with other test methods,the tester has faster test speed and more accurate test results,and can be widely used in VGA data cable manufacturers.更多还原
