Abstract
A power line carrier modem is configured for coupling to AC power lines. The power line carrier modem includes a processor, an output from the processor, a plurality of inputs to the processor, and a directional coupler operatively connected to the output, the plurality of inputs, and the AC power lines. The power line carrier modem may further include a digital-to-analog-converter operatively connected to the output from the processor. The output from the processor may be an output bus. The power line carrier modem further includes an analog-to-digital-converter operatively connected to the plurality of inputs to the processor. The power line carrier modem may be configured to perform Vector Network Analysis functions. The power line carrier modem may be configured to indicate PLC modem transmit frequencies being reflected from the AC power lines or the line coupler. The transmitter functions may be implemented in software by the processor to provide a transmit output on the output line. Receiver functions may also be implemented in software by the processor.
