我们提出了一种基于紧凑型现场可编程门阵列 (FPGA) 的脉冲定序器和射频 (RF) 发生器，适用于冷捕获离子和原子的实验。该装置能够输出至少 32 个晶体管晶体管逻辑 (TTL) 通道的脉冲序列，定时分辨率为 40 ns，并包含一个内置的 100 MHz 频率计数器，用于对来自光电倍增管的电脉冲进行计数。有 16 个独立的直接数字合成器 RF 源，具有快速（上升时间类似于 60 ns）幅度切换和 0 至 800 MHz 的亚 mHz 频率调谐。 (C) 2015 AIP 出版有限责任公司。
We present a compact field-programmable gate array (FPGA) based pulse sequencer and radio-frequency (RF) generator suitable for experiments with cold trapped ions and atoms. The unit is capable of outputting a pulse sequence with at least 32 transistor-transistor logic (TTL) channels with a timing resolution of 40 ns and contains a built-in 100 MHz frequency counter for counting electrical pulses from a photo-multiplier tube. There are 16 independent direct-digital-synthesizers RF sources with fast (rise-time of similar to 60 ns) amplitude switching and sub-mHz frequency tuning from 0 to 800 MHz.
