Description

technical field [0001] The invention relates to a test system, in particular to a power line network product test system. Background technique [0002] Power Line Communication (PLC) technology refers to a communication method that uses power lines to transmit data and media signals. This technology is to load the high frequency carrying information on the current, and then use the power line to transmit and receive the adapter to separate the high frequency from the current and transmit it to the computer or telephone to realize the information transmission. [0003] The power line network product is a kind of network product based on PLC. As the name suggests, power line network products can also access the Internet through power lines. Where there is a power outlet, there is a network. However, power line network products have the following disadvantages in practical applications: [0004] 1) Noise interference on the power line has affected the quality of signal trans...

AI Technical Summary

Problems solved by technology

[0004] 1) Noise interference on the power line has affected the quality of signal transmission, resulting in a decrease in throughput performance;

[0005] 2) The wiring of the power line network is long and there is a large attenuation, which also affects the transmission quality and throughput performance of the signal

[0006] Due to the complexity and diversity of power line noise interference, it is difficult for power line network products to be widely promoted and applied

However, the existing technology focuses on PLC performance testing based on power line network attenuation, and does not involve related tests based on power line noise interference.
