Design of BSR_2 broad band seismic recorder
BSR_2宽频带地震记录仪的研制

As a new generation digitizer, BSR-2 broad band seismic recorder adopt advanced computer and electronics technologies such as the double CPU structure, the precise timing service combined of GPS receiver and OCXO digital clock, the 24-bit Delta-Sigma A/D converters, the mass on-site data storage system, the build-in self-test method and so on. The ideal acquisition device can be widely used in the observation of ground motions caused by local and distant earthquakes, artificial explosions, vibrators and other natural and human induced activities. It is a reliable and convenient seismic data acquisition system with a high ratio of property to price.
