摘　　要：V93K在测试IC电特性的输出延迟时间时,遇到要求测试负载电容不超过10pF,而V93K数字通道的负载电容在30pF以上,无法直接进行编程测试。采用外挂示波器进行测量,其探头的电容可达8pF以内。V93K在运行功能向量过程中读取到示波器的测量结果,延迟时间参数达到被测器件的指标要求范围之内,测试时间在6s内完成,不但解决了手动测试效率低的问题,而且该方法测量准确,可操作性强。In testing a device electrical characteristic of output delay time with V93K, meeting the requirements for testing in load capacitance is less than 10 pF conditions, but the V93K digital channel's load capacitance is above 30 pF, which cannot be tested in follow-up work. To solve this problem is measured by the oscilloscope, the probe capacitance of which up to 8 pF. The V93K runs the function vector in testing delay time, reads the measurement result form oscilloscope, the test result is under the device's index, completed in 6 seconds, save a lot of time cost. Many experimental results show that, the method of measuring result is accurate, the maneuverability is feasible.
