摘要
目前,磁通门磁力仪广泛应用于观测地球磁场相对变化的仪器。相对于应用,仪器的性能测试不为人们所熟悉。本文针对GM4型磁通门磁力仪的噪声特性,频率特性,线性度,温度特性等关键性能指标的测试依据、测试方法及流程给予详细的阐述。
Fluxgate magnetometer has been used widely as the geomagnetic field vector measurement instrument. To compare with the application, the testing process of the device characteristics is not familiar by people. The principle,method and flow of the key performances, including the frequency response, noise, linearity and temperature coefficient are introduced in this paper
