TDE系列地震数据采集器

TDE series seismic data acquisition system

TDE系列地震数据采集器是一套 16位 (TDE - 2 16C) / 2 4位 (TDE - 2 2 4C)地震数据采集器。该采集器为低功耗、程控增益、现场模数转换 ,其带宽为 ( 0～ 2 0Hz) ,动态范围为 90dB (TDE - 2 16C) / 12 0dB (TDE - 2 2 4C)。采集器通过接收GPS信号产生精确定时。介绍了该采集器的技术设计方案。

TDE Series Seismic Data Acquisition System is 16 bits (TDE-216C)/24bits(TDE-224C) seismic digitizer.It is a low-power, programmable gain amplifier, a remote analog-to-digital converter system designed to process high quality data. It is specifically designed for broadband recording (0～224C).It can produce precise timing information by receiving GPS signals. TDE Series Seismic Data Acquisition System has been installed in Guangzhou,Fujian,Xianmen,PanYu,Liuzhou,Shenzhen, Zhanjiang and Tangshan etc. It has been connected with DS-1, JC-V100, FBS-3A, S-13, BB-13, JD-1 seismometer etc and it has detected and located a great quantity of seismic events exactly. TDE Series Seismic Data Acquisition System was appraised in July, 1998.
