The status quo of high-resolution data acquisition system is discussed and by studying the character of high-resolution seismic exploration and seismic signal, the theoretical models and character of each unit are gained. This paper point out that under 1000 meter's depth where petroleum is embedded the IDR of central controlled seismic instrument and telemetricseismic instrument are lower than 70dB which can't meet the needs of high-resolution seismic exploration.

文章论述了当代高分辨率地震数据采集系统的现状，对高分辨率地震勘探及地震信号特点进行了研究，得出了高分辨率地震勘探数据采集系统的理论模型和各功能单元的理论特性，指出在石油与天然气埋藏的千米以下的地层，集中式数字地震仪和24位遥测地震仪的瞬时动态范围均不超过70dB，远远满足不了高分辨率地震勘探的需要。

This paper introduces the research and implementation of all-purpose high-speed test adapter for ADC. The main contents includes two methods about how to testing the static parameters and dynamic parameters for ADC. The servo loop method is proposed to static parameters, by using the test principle of high-precision voltage source, high-precision voltage meter and digital comparator. To dynamic parameters, the DDS chip of AD9851 is used to generate sine waves with high signal to noise ratio, then the high-s...
