| Abstract: | Intermodulation and cross-modulation interference are two kinds of rather harmful interference which often appear in CATV system.This paper analyzes intermodulation and cross-modulation interferene emergence mechanism,introduces the method of intermodulation and cross-modulation interference measurement and the suggestion of process measurement result.At last,it probes into system adjusting method which not only transmits more information channels but also avoids intermodulation and cross-modulation interference and the method feasibility. |
