Scorpion模拟单元BITs测试项目及测试原理

Test items and test theory of Scorpion analog unit BITs

地震勘探仪器是地球物理勘探施工中的重要设备,其工作状态的好坏直接影响到采集资料的品质,通过对地震仪器及其采集单元和外接设备定期进行BITs测试,就可以监控它们的性能状况。本文从BITs测试的基本概念入手,介绍了BITs测试信号产生电路的组成和工作原理,并细致地阐述了BITs测试的十多个测试项目的概念、测试方法及数学计算模型等。

Geophysical seismic exploration instrument is very important in geophysical prospecting. The working conditions of instrument have a direct impact on the quality of seismic data. Though a regular basis BITs tests on the instrument and external devices, we can monitor the status of their performance. This paper introduces the basic concept and theory of BITs, describes the testing methods, test items and mathematical models.
