摘要
基于SET-3000型传感器实验平台,选用高精度运算放大器芯片配合滤波电路对平台的调理电路进行了改进,缓解了系统灵敏度低,线性度差等问题。利用Labview对实验数据进行拟合分析,表明采用改进后的调理电路提高了实验装置的静态参数性能。
The topic selects high precision operational amplifier matched filter circuit for SET-3000 Sensor Experimental Platform which is made by conditioning circuit.It is used to solve influences of low sensitivity,nonlinearity and other problems.Through Labview fitting analysis,it shows that the new conditioning circuit can improve sensitivity and linearity of the test device.
