摘　　要：介绍了HP3562A频谱分析仪用于采集电磁干扰中的电场、磁场方法技术,并将该技术用于矿区野外电磁干扰现场测量。通过现场对电磁干扰信号的数据采集和频谱分析,可研究矿区电磁干扰信号的特性,为矿区开展电磁法勘查,以及研究矿区抗电磁干扰的电磁法采集技术提供科学依据。The technique of collecting electrical and electromagnetic fields mixed with EM noises by using HP3526A spectrum analyzer has been introduced in the paper. The technique has been applied for field measurements of noises in mines. Through field acquisition and spectral analyses of EM noises, the characteristics of the noisy signals could be studied, so providing a basis for developing a data acquisition technique of anti-interference EM survey.
