DZSS-1型深层数字地震仪由三分量检波器CDJ-6B、数据采集单元、磁带机、编码钟和回放装置组成。它采用循环浮点放大—A/D转换技术、低噪音运算放大器、CMOS器件,使仪器噪音小于0.3μV(折合到前级放大器输入端,均值),动态范围大于96dB,采用调相制、串码、单轨盒式数字磁带记录。仪器频带范围1—30Hz,浮点72dB。有钟差显示(±1ms)、噪音和误操作显示。仪器主要技术指标(道间一致性、漂移、噪音、串音、误码率、主放台阶精度)可用微机进行检测,能满足地震测深和其它低频数字测量之用。
DZSS-1 deep digital seismograph by the three component detector CDJ-6B, data acquisition unit, tape drive, encoding clock and playback device. It uses circular floating-point amplification-A / D conversion technology, low noise op amp, CMOS devices, the instrument noise is less than 0.3μV (equivalent to the preamplifier input, mean), dynamic range greater than 96dB, Yards, monorail box digital tape recording. Instrument frequency range 1-30Hz, floating point 72dB. Clock display (± 1ms), noise and misoperation display. Instrument main technical indicators (inter-channel consistency, drift, noise, crosstalk, bit error rate, main amplifier step accuracy) can be used computer testing, to meet the seismic sounding and other low-frequency digital measurement purposes.
