长期以来，示波器一直只是用于调试 JTAG（IEEE 1149.1）信号完整性问题，Keysight Infiniium 系列示波器是最先支持 JTAG 协议解码的示波器。虽然需要进行 JTAG 解码的情况非常少见，但是手动解码 JTAG TAP 控制器状态（包括指令和数据寄存器数值）的过程很困难，既费时又容易出错。用于 Infiniium 9000、90000 和 90000 X 系列示波器的 N8817A JTAG 解码选件可以对在示波器通道或数字通道（MSO 通道）上捕获的 TMS、TDI、TDO 和 TCK 信号进行 JTAG 解码。它能够从工业标准 BSDL 文件导入器件的名称和操作码，实时显示 JTAG 协议，并标记出特定类型的错误条件。
多选项卡协议查看工具包括搜索功能以及波形与选定数据包关联功能，使您能够使用时间关联的跟踪游标，在物理层信息和协议层信息之间快速切换。
