Due to the subtle error among different manufacturing equipment, the gate delay of circuits is different and varies in a given scope, which induces the time uncertainty of the waveform.

由于制造设备本身存在微小误差，具体门的延时并不相同，而是在一定范围内变化，引起波形变化的时间不确定。

Figure 2 - In the Run event, you see the code simply reads the waveform back from the scope.

图2 -在运行事件中，您看到的代码是用来读取示波器的波形。
