Keysight 70900B 是适用于模块化频谱分析仪和监视接收器的主控模块。它也是光波信号分析仪的部件。Keysight 70900B LO在Keysight 70000频谱分析仪中有两项主要功能：作为合成型本地振荡器（LO）和作为系统的主控模块。作为频谱分析仪本地振荡器，它会影响相噪、稳定度和频率精度。Keysight 70900B使分析仪在10kHz载波偏置时有-108dBc/Hz的优异相噪性能。合成技术具有毫赫兹的分辨率，可用于精确的频率控制。LO的快调谐速度直接与分析仪的调谐速度相关。作为主控模块，Keysight 70900B确定系统特性、副模块控制、命令处理速度和GPIB速度。硬件和处理功能的结合为监视应用和自动测试提供了快速的调谐。
停产通知：除 71612C 12Gb/s 差错性能分析仪、71501D抖动分析系统、E5500 相噪系统和 JS-1000 抖动系统外，Keysight 模块化测量系统（MMS）产品将于2003年10月停产。
