特性和优点

多个输入端口

在相同或不同频率下捕获相位相参信号

在相同或不同频率下捕获宽带调制相位相参信号，拓展了新的测量应用场景。FSWX 是首款提供此功能的多通道信号与频谱分析仪。

  • 将放大器或混频器的输出信号与输入的调制参考信号进行比较
  • 轻松测量波束赋形雷达或 MIMO 通信系统中各个天线之间的相位关系，深入了解被测系统
  • 在部署 DRFM 或雷达发射机的电子战场景中同时捕获不同频率下的信号，从而提供全面的态势感知，提高威胁检测能力。

互相关

测量低至物理极限的噪声

FSWX 是首款具有互相关功能的信号与频谱分析仪。互相关技术消除了分析仪的固有噪声，有助于清晰查看被测设备的特性。这种方法能够将噪声降到物理极限，从而为噪声、相位噪声和 EVM 测量或杂散搜索提供更大的动态范围。 优点：

  • 前所未有的灵敏度
  • 将相位噪声降到最低
  • 出色的动态范围
  • 一流的 EVM
  • 低功率下的高电平精度

宽带 ADC

最高达 8 GHz 的分析带宽

FSWX 是一台宽带宽仪器。每个模拟信号路径都端接到一个提供 8 GHz 分析带宽的高分辨率、高速 ADC。这包括以下特性：

  • 在所有输入频率下提供全分析带宽
  • 在频谱模式下提供最快扫描速度
  • 为 EVM 测量和杂散搜索提供高动态范围

滤波器组

带可选 YIG 预选器的默认滤波器组

FSWX 配有滤波器组，在整个仪器频率范围内有独立的高通和低通滤波器。相较于扫频预选滤波器，滤波器组具有以下优势：

  • 在整个频率范围内提供超高精度
  • I/Q 分析经过预选。滤除其他频率的信号，不会像图像一样混叠到感兴趣的频率范围
  • 扫描速度非常快
YIG 滤波器选件可以满足严苛的动态范围需求。
