摘要

为了测量电子器件周围的磁场噪声，我们开发了一种使用三轴搜索线圈的测量系统。三轴搜索线圈传感器之间的正交搜索线圈串扰小于-40 dB。在1khz时，测量到的搜索线圈的磁灵敏度为10 pT//spl径向/Hz。

Development of a magnetic field measurement system using a tri-axial search coil

In order to measure the magnetic field noise around electric devices, we developed a measurement system using a tri-axial search coil. The crosstalk of the orthogonal search coils is less than -40 dB between the tri-axial search coil sensors. The measured magnetic sensitivity of the search coil is 10 pT//spl radic/Hz at 1 kHz.
