Abstract
The current test equipment of PLC communication performance, which has low accuracy and poor reliability in the aspect of anti-interference performance test.The technical of test system and key technical of anti-jamming test are analyzed.This paper focuses on electromagnetic conduction and radiation crosstalk and multipath interference in the frame of test system, the inaccuracy and instability of LC attenuator and matrix are briefly described, and puts forward the improvement plan.Based on the key components such as high performance EMI filter, shielding box and coaxial programmable attenuator, the existing test system is improved.After the receiving sensitivity and the demodulation threshold SNR test, the test process is more stable, and the test results are more reliable and more precise, the results verify that the improved scheme is suitable for point-to-point communication performance test, and also can be applied to the test of the PLC communication network route capacity.关键词
