| Abstract: | 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 |
