自主频谱扫描
自主频谱扫描和卫星通信载波识别
R&S®GSACSM 分类功能支持系统自主扫描频谱信号并识别载波。载波可显示在彩色图表和列表中。图表和列表元素便于轻松识别每个载波。手形工具便于用户添加新区域，以便选择特定载波进行进一步处理。所有收集的信号参数和星座图均清楚显示。
载波叠加检测
通过载波内载波检测识别底层信号
使用R&S®GSACSM的PCMA检测和信号识别系统能够检测和识别成对载波多址信号（具有相同载波频率和波特率的两个载波）。使用载波下检测来识别有用信号下不需要的不对称信号源，从而识别可疑干扰源。
DVB-CID 解调
DVB-CID信号的连续频谱扫描与解调
现代卫星通信表现出许多需要有效避免的信号干扰。数字视频广播组织指定了一个载波ID（CID）来标识主机载波，有效地减少了卫星信号之间的干扰。
R&S®GSACSM可以处理CID信号，也就是说，它们将被检测并解调。将提取特定于CID的“全局唯一ID”、GPS坐标和电话号码。
连续载波监测
通过多通道服务调度表轻松监测载波
R&S®GSACSM 使用多通道服务调度表监测信号参数。R&S®GSACSM 能够设置报警阈值，以在出现无用信号的时候通知用户。用户可以定义频谱信号模板，以确保立即识别每一个可疑载波。
分布式网络结构
可扩展的客户/服务体系结构
在可扩展的客户/服务体系结构中，R&S®GSACSM允许在分布式系统中进行远程频谱分析。操作员可以在不同的位置管理他们的仪器（射频组件，如R&S®NRQ6）。
