Keysight 44478B 多路复用器模块是高频或快速脉冲信号宽带转换的理想选择。 双 1 至 4 多路复用器可为直流至 1.3GHz 的信号提供双向转换功能。 高通道隔离度（1 GHz 时，>55 dB）支持用户使用频谱分析仪、网络分析仪或矢量分析仪完成高质量的动态范围测量。 每款 1 至 4 多路复用器均在“树形”结构中包含七个继电器，可提供高隔离度和低 VSWR（电压驻波比）。 模块边沿的所有连接器均为 BNC（阴头）型，可简单进行布线。 离线通道（off-channel）可在电阻器中负载端接，以维持被测器件电路的正常工作。 只需将 50/75 欧姆 SMB 型电阻端接插入到每通道提供的板上 SMB（阳头）连接器。
