    • Apparatus and/or method for performing single-shot network analysis of electrical, electronic and electro-optical elements (e.g., components, circuits, modules, sub-systems and/or systems) on a device, or devices, under test (DUT). A pulsed optical source is directed through a first dispersion element to an modulator, while a delayed version of the pulsed optical source is directed to the DUT (pulsed optical source converted to electrical signal if DUT has electrical input), whose electrical output is fed to the modulator whose modulated optical pulse output is stretched through a second optical dispersion element, then converted to an electrical signal and processed to provide analysis and/or display of DUT response.
    • 用于执行设备上的电气,电子和电光学元件(例如,组件,电路,模块,子系统和/或系统)的单次网络分析的装置和/或方法, 或被测器件(DUT)。 脉冲光源通过第一色散元件被引导到调制器,而脉冲光源的延迟形式被引导到DUT(如果DUT具有电输入,脉冲光源被转换成电信号),其电输出被馈送到 调制器的调制光脉冲输出通过第二光色散元件被拉伸,然后被转换为电信号并被处理以提供DUT响应的分析和/或显示。

    • A communication system includes a master host unit that communicates wireless spectrum with a service provider interface using analog spectrum. Master host unit communicates digitized spectrum in N-bit words over a digital communication link. Master host unit converts between analog spectrum and N-bit words of digitized spectrum. Communication system includes hybrid expansion unit coupled to master host unit by digital communication link. Hybrid expansion unit communicates N-bit words of digitized spectrum with master host unit across digital communication link. Hybrid expansion unit converts between N-bit words of digitized spectrum and analog spectrum. Hybrid expansion unit communicates analog spectrum across analog communication link to analog remote antenna unit. Analog remote antenna unit communicates wireless signals using first antenna. Communication system further includes a switch in a data path between service provider interface and antenna. The switch selects between transmit path and receive path in response to switching control signal.
    • 通信系统包括使用模拟频谱将无线频谱与服务提供商接口进行通信的主主机单元。 主机单元通过数字通信链路以N位字通信数字化频谱。 主机单元在模拟频谱和数字频谱的N位字之间进行转换。 通信系统包括通过数字通信链路耦合到主主机单元的混合扩展单元。 混合扩展单元通过数字通信链路将数字化频谱的N位字与主主机通信。 混合扩展单元在数字化频谱和模拟频谱的N位字之间进行转换。 混合扩展单元将模拟频谱通过模拟通信链路传送到模拟远程天线单元。 模拟远程天线单元使用第一个天线来传送无线信号。 通信系统还包括在服务提供商接口和天线之间的数据路径中的交换机。 交换机响应于切换控制信号,在发送路径和接收路径之间进行选择。
