摘要
The present disclosure is directed to systems, apparatuses, and methods for monitoring the frequency spectrum of signals transmitted by a PLC device over a PLC network to detect and correct potential EMC regulation violations due to intermodulation (IMD) products created by the interaction of the transmitted signals with one or more non-linear devices on the PLC network. Once an IMD issue is detected, the systems, apparatuses, and methods can reduce the injected power of signals transmitted by the PLC device at the frequencies (or range of frequencies) that result in a EMC regulation violation. In addition, the systems, apparatuses, and methods can reduce the injected power of signals transmitted by the PLC device at all times or during times that the non-linear devices are interacting and generating IMD products.
