HP3070中的数字电路内故障该怎么解决？

嗨大卫，这可能是一个边缘测试，传递一个系统而不是另一个系统，可能是由于时间问题，这个错误与电压存在有关 - 你应该检查原理图上列出的节点及其可能的固定节点或
有力量存在。
所以检查你是否没有开到有电压存在的节点这是数字子器官中的第一次测试吗？
可能是你需要将测试移到数字例程的中间或尝试缩短向量周期并在测试中接收每个100n的延迟（即如果向量周期为400n，则变为300n，如果接收延迟为300n，则更改
到200n）你无论如何都不能改变160n以下的矢量周期，谢谢，Jon

  Hi David,

this is probably a marginal test that passes on one system but not on another and could be due to timing, this error is related to voltage being present- you should check that node listed on the schematics and its probablky a fixed node or has power present.

so check that you are not driving onto a node that has voltage present

is this the first test in the digital suborutine ? could be that you need to move the test to middle of digital routine or try to shorten the vector cycle and receive delay inside the test by 100n each (i.e. if vector cycle is 400n, change to 300n, and if receive delay is 300n, change to 200n) you wont be able to change vector cycle below 160n anyway ,


thanks, Jon
