Maximum source frequency1
NI 66012
Without prescaling................... 20 MHz
With prescaling........................ 60 MHz
NI 6602
Without prescaling................... 80 MHz
With prescaling........................ 125 MHz
Minimum source pulse duration3
Without prescaling.......................... 5 ns in edge-detection mode
With prescaling ............................... 3.5 ns in edge-detection mode
Minimum gate pulse duration ................ 5 ns in edge-detection mode
这是6602的参数
如果用边沿技术的方式的话，你的应用肯定可以
Minimum pulse width
NI 6601 ........................................... 50 ns
NI 6602 ........................................... 200 ns
这是测宽的最小值
看你如何应用了
