自动同步总线（AS总线）桥可使多个数字转换器模块同步工作，负责所有必需的触发信号和时钟信号的分配。
同步数字转换可以改善跨通道测量的精度，对于精确时间校正必不可少。AS总线系统可以对所有数字转换器进行相位同步，使它们符合某个外部标准（例如10 MHz参考信号）；也可使用任意触发输入（通道或外部触发输入）作为系统中所有其他数字转换器的触发信号源，从而增加触发的灵活性。AS总线电路允许选定的时钟和触发信号通过所有连接的模块进行传播。系统可以自动检测每个卡的位置，从而校准单独的通道时间延迟，使所有连接的ADC都具有相同的时钟。
AS总线系统的软件还有一个非常简单的功能，可以把多个数字转换器组合成一个具有多个通道的单一仪器。
