摘要
ＴＥＬＳＥＩＳ ＳＴＡＲ无线遥测地震仪主机与天线之间采用了天线前置放大器，以补偿射频信号在电缆中的损耗，增大仪器的有效传输距离。文章介绍了该部分电路的工作原理，并简要分析了电路，对使用中出现的几种常见故障提出了判断和解决的方法。
The TELSEIS STAR is a telemetry seismic instrument.There is a preamplifier between its recorder and the system antenna. It is used for redressing the transmission loss of radio frequency signal in the cable and increasing the efficient RF radio range.This paper describes its working principle, analyzes its circuit and gives out some solving methods of common faults.
