在和田地震台阵中心子台安放9台CMG-40T型短周期地震计，采用EDAS-24IP数据采集器进行数据采集。对同一时段观测数据的地动噪声功率谱、动态范围等参数进行测定，并对测定结果进行对比，在使用者的角度分析该类型地震计的一致性。

CMG-40T short period seismometers were installed in the central substation of Hetian array. The data was collected by EDAS-24IP data acquisition unit. We determined the ground motion noise power spectral, dynamic range of observation data at same time and analyzed the test result comparatively. The consistency of this kind seismometer was obtained for users.
