摘要
在POI系统中,由于多系统接入导致互调干扰严重且复杂,目前常用的互调测试系统很难满足POI系统无源互调的测试要求,甚至无法测量。通过介绍传统的无源互调测量方式,对POI无源互调测量面临的问题进行分析,并在此基础上提出了一种POI系统无源互调测量的解决方案。该方案不仅能够解决POI系统无源互调的测量问题,而且可以实现全自动测量,测试效率非常高。
In POI system, passive intermodulation interference due to multiple system accesses becomes more serious and complex. At present, the commonly-used passive intermodulation test system is very difficult to satisfy the test requirement of passive intermodulation for POI system, or impossible to be measured. Firstly, the traditional method of passive intermodulation measure（PIM） was introduced and potential problems of POI PIM were analyzed. Based on this, a solution to POI system PIM was presented. The solution not only solves POI system PIM, but realizes fully automatic measurement with very high efficiency.
