ELECTROMAGNETIC INTERFERENCE SELF-CONTROL SYSTEM AND OPERATION METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide an electromagnetic interference self-control system and an operation method therefor which can perform an inspection of electromagnetic interference on power supply ports and signal ports for a communication network at the same time.SOLUTION: An electromagnetic interference self-control system comprises: a signal source; a LISN (line impedance stabilization network); a CDN (coupling decoupling network); an ISN (impedance stabilization network); and a receiver, in order. The signal source comprises a power supply port and provides stable signals. The LISN comprises a LISN power supply port and a LISN wireless frequency port. The CDN comprises a CDN signal port and a CDN wireless frequency port, and couples input signals to the CDN wireless frequency port onto the CDN signal port to adjust impedance suitable for a signal conduction path. The ISN comprises an ISN signal port and an ISN wireless frequency port. The receiver measures and figures out signal strength of each frequency point.
