Experiments in Atomic, Molecular, and Optical (AMO) physics require precise and accurate control of digital, analog, and radio frequency (RF) signals. We present control hardware based on a field programmable gate array core that drives various modules via a simple interface bus. The system supports an operating frequency of 10 MHz and a memory depth of 8 M (223) instructions, both easily scalable. Successive experimental sequences can be stacked with no dead time and synchronized with external events at any instructions. Two or more units can be cascaded and synchronized to a common clock, a feature useful to operate large experimental setups in a modular way.

基于现场可编程门阵列的原子物理实验控制硬件

原子、分子和光学 (AMO) 物理实验需要对数字、模拟和射频 (RF) 信号进行精确和准确的控制。我们提出了基于现场可编程门阵列核心的控制硬件，该核心通过简单的接口总线驱动各种模块。该系统支持 10 MHz 的工作频率和 8 M (223) 条指令的存储深度，两者都易于扩展。连续的实验序列可以无死区叠加，并在任何指令下与外部事件同步。两个或多个单元可以级联并同步到一个公共时钟，这一功能对于以模块化方式操作大型实验装置很有用。
