Keysight E1333A 3 通道通用计数器是 B 型、1 槽、使用寄存器的 VXI 模块。该模块可提供电子测试应用所需的功能。您可以将三个信号连接至一个计数器卡，并在它们之间进行多路传输，从而进行频率测量。计数器功能包括频率、平均周期、脉冲宽度和平均脉冲宽度、时间间隔和平均时间间隔、累加以及比率。
您可以直接选择以秒为单位的分辨率、要平均的周期数量、间隔数量或跳变数量。此外，您还可以测量通道间跳变的时间间隔，或测量通道 1 和 2 或通道 2 和 1 之间的频率比率。
如欲完善 E1333A 模块的功能，您还可以通过软件命令选择上升沿或下降沿，并且对通道 1 和 2 的跳变进行计数。输入信号调整命令可同时控制所有的通道。触发器电平/灵敏度命令可用于每一个通道。
