Basic Level Trigger Detection函数用法帮助
大家好，请问波形检测中的Basic Level Trigger Detection函数怎么用，其中的hysteresis 节点是什么意思啊，看了帮助不是很明白。帮助如下，请高手指点hysteresis specifies the amount above and below level through which each signal contained in signal in must pass before a trigger level crossing is detected. Trigger hysteresis is used to prevent noise from causing a false trigger. For a rising edge slope, the signal must pass below level – hysteresis before a trigger level crossing is detected. For a falling edge slope, the signal must pass above level + hysteresis before a trigger level crossing is detected. 这个是检测信号触发的，Level是你开始CHECK的标准幅值，
hysteresis是滞后多少，
LV中有个例子，你可以看下
