SN338B数字地震仪道间串音的研究

ASTUDY ON THE CROSSTALK INTERFERENCE AMONG SEISMIC CHANNELS IN SN-338B DIGITAL SEISMIC ACQUISITION SYSTEM

重庆地质仪器厂

本文研究了SN338B数字地震仪道间串音指标不高的原因,介绍了为探索此道间串音来源所进行的试验工作,并提出改进道间串音指标的措施。

We have found the cause for why the specification of crosstalk among seismic channels was set not so stringent as it should be for SN-338B digital seismic acquisition system. In this paper, we'll show the readers how the work has been conducted for this study and offer an approach by which the crosstalk among channels in SN-338B seismic acquisition system is reduced to certain extent.
