图形传输系统包括计算机模块、PCIe 转换器模块、多组数据传输模块、14槽 AXIe 机箱、外接同步信号产生器以及磁盘阵列(RAID)系统，如图2所示。
在电子束打印期间，计算机模块通过 6 Gbps 的SAS接口，自数据中心(也就是磁盘阵列系统)实时的存取集成电路图文件至系统上的内存储存。PCIe切换器模块位于分享器插槽(hub slot)，提供PCIe 通道自动切换功能，负责将储存于内存的集成电路图文件，通过PCIe高速数据接口传输至不同的数据传输模块。每个传输模块均可支持 72 组光纤输出通道。外部同步信号产生器则产生一组共同工作频率及触发信号来让多个机箱可同步运作。
AXIe 大部分独特的功能都被图形传输系统所采用，包括：机构设计及组装、硬件平台管理及监控机制、电源分配机制、主动散热系统以及数据传输接口。
E-Beam系统机箱内为较为复杂的同步化，须利用 AXIe STRIG 及 SYNC 信号，如此可确保点触发系统达成规定的各槽极***与低抖动的同步化。
通道间时钟偏移 (Channel-to-channel skew)
E-Beam 系统的硬件设计可确保通道间的时钟偏移***大不超过 2ns。自外部同步信号产生器开始，低偏移扇形输出缓冲器(fan-out buffer)即用于外部同步信号产生器之中，做为将工作频率及同步信号分配到各机箱切换模块的用途。另外，切换模块除提供 PCIe总线自动切换功能外，也负责切换 STRIG、SYNC及相关频率信号，将这些同步信号分配到各插槽上的数据传输模块。在数据传输模块方面，除特别注意各频率及数据信号在PCB上布线都须使用相等路径长度外，在电路输出部分也都采用低偏移缓冲器。***后处理过的数据会由***ago 平行光纤*** (AFB-810BHZ-TX) 输出。综合考虑 FPGA 内部绕线及制程、光纤、连接器及 PCB 路径等因素后，计算所得的总体通道间时钟偏移可小于 1ns 以下。
