Description

一种检测方法及装置 技术领域
本申请涉及但不限于通信领域，尤其涉及一种检测方法及装置。
背景技术
目前的分体式微波系统基本由IDU(室内单元)和ODU(室外单元)两部分组成。IDU与ODU之间通过中频馈线实现互联与通信，中频信号在一根线缆上的传输走向是：中频信号1从IDU1到ODU1，再从ODU1到ODU2，最后从ODU2到达IDU2，IDU-ODU-ODU-IDU这样一条完整的信号传输路径俗称为“一跳”；同时，另一中频信号2可以从IDU2到ODU2，再从ODU2到ODU1，最后从ODU1到达IDU1。中频馈线上复用了多组不同频段的模拟信号。以某一型号的微波设备为例，中频线缆上复用的信号包括：IDU发送的350MHz载波信号，IDU接收的140MHz载波信号，IDU向ODU供电的-48V直流信号等等。
对于IDU的性能或故障检测，目前都是采用搭建IDU-ODU-ODU-IDU这样的一跳环境联调验证，这种方式有诸多不便，例如：ODU的成本很高、环境搭建复杂、ODU的高频辐射对测试人员产生不良影响，同时由于IDU和ODU之间的数据及控制信号都是通过一根射频线缆“复用”在一起进行传输的，通过一跳这样的方式很难针对一组信号进行检测，常常需要在现场借助大量的对比验证，要求维护人员具备相当的专业技术知识，并且很有可能需要后方研发人员的支持才有能完成。
