RFFE 协议分析仪和练习器
Model No: PGY-RFFE-EX-PD
RFFE 协议分析仪 (PGY-RFFE-EX-PD) 是一款具有多种功能的协议分析仪,用于捕获和调试主机与受测设计 (DUT) 之间的通信。射频前端控制接口 (RFFE) 串行总线接口正成为控制射频前端设备的首选。前端设备多种多样,如功率放大器 (PA)、低噪声放大器 (LNA)、滤波器、开关、电源管理模块和天线调谐器。它广泛应用于移动设备中。
PGY-RFFE-EX-PD 是领先的仪器,设计和测试工程师可以通过将 PGY-RFFE-EX-PD 配置为主机/从机、生成具有错误注入能力和幅度变化的 RFFE 流量以及解码 RFFE 协议数据包,来测试 RFFE 接口是否符合其规范。

多域视图
多域视图在单个 GUI 中提供 RFFE 协议活动的完整视图。用户可以使用 GUI 或脚本轻松设置分析仪以生成 RFFE 流量。用户可以从设置菜单中设置不同的触发条件,以捕获特定事件的协议活动,并解码主从机之间的协议事务。解码结果可以在具有自动关联功能的时序图和协议列表窗口中查看。这种全面的信息视图使其成为行业领先的解决方案,为调试 RFFE 协议活动提供了易于使用的工具。
练习器
PGY-RFFE-EX-PD 支持使用 GUI 和脚本生成 RFFE 流量。用户可以使用 GUI 生成简单的流量来测试 DUT。基于脚本的 GUI 提供了模拟真实世界中完整预期流量(包括错误注入)的灵活性。在此示例脚本中,用户可以生成如下 RFFE 流量:
- 脚本第 4 行:向 USID 为 5 的从机写入寄存器 (REG Write)
- 脚本第 5 行:从 USID 为 5 的从机读取寄存器 (REG Read)
- 脚本第 8 行:向 USID 为 5 的从机写入扩展寄存器 (EXT REG Write)
- 脚本第 9 行:从 USID 为 5 的从机读取扩展寄存器 (EXT REG Read)
时序图和协议列表视图
时序视图提供带有总线图的 SCLK 和 SDATA 信号图。在数字时序波形上叠加协议位将有助于轻松调试协议解码数据。光标和缩放功能方便在时序图中分析任何时序错误的协议。
协议窗口提供每个状态下的解码数据包信息和所有数据包详情。在协议列表窗口中选择的帧将在时序视图中自动关联,以查看数据包的时序信息。
强大的触发功能
PGY-RFFE-EX-PD 支持自动、简单和高级触发功能。分析仪可以针对任何协议数据包进行触发,例如扩展寄存器写入、扩展寄存器读取等消息。高级触发提供了监控多个触发条件的灵活性,并可以设置多状态触发机。
