摘　　要：SN38 8仪器是国内地震勘探的主要仪器之一。文章通过对相关资料的分析 ,详细介绍了用MACHA编译码器实现SN388仪器主从接收的原理及产生主仪器RFTB延迟大于从仪器RFTB延迟的原因。SN388 seismographer is one of major seismograph used in seismic prospecting at home. Through analysis of relative data, the paper introduced in detail the principle how to use MACHA coder/decoder to start master/slave mode of SN388 seismographer and described the reason that the delay of RFTB resulted from SN388 master is larger than that from Slave.
