“Geopro”8012型信号处理地震仪,实质上是一个微处理机为基础的计算机。具备模拟输入、数字转换、可视图形显示和硬拷贝输出。与BISON在1969年首创信号增强相同,这种十二道信号处理地震仪在手持式地震仪方面又是一重大改进。用8012可做: The “Geopro” Model 8012 Seismograph is essentially a microprocessor-based computer. With analog input, digital conversion, visual graphics and hard copy output. The same as BISON’s first signal enhancement in 1969, the twelve signal-processing seismometers are another major improvement in hand-held seismometers. Use 8012 to do:
