Improvement of anti-interference capacity of System Four's A-unit and lowering power consumption.

Tang Mingwen,Xiang Xudong,Cui Bing and Wang Peng.  
The System Four acquisition unit is characterized by poorer anti-interference ability and higher power consumption.Through analyzing the control circuit of System Four's A-unit,using system test program and by the aid of oscillograph and digital multimeter,the paper performs reformation of relevant circuit: increasing protect circuit in order pair of A-unit,input end of data pair and power of A-unit;changing elements with poorer property,which improves anti-interference capacity of A-unit and lowers the power consumption of A-unit.
