针对移动通信基站周围电磁环境监测,目前国内常用便于携带、操作简便的宽带综合场强仪。宽带综合场强仪进行电磁环境监测时,只能获取某一空间位置的综合电场强度值,当周围电磁辐射源情况较为复杂时,无法准确判断主要辐射源。在国外,宽带综合场强仪已逐步被选频式辐射测量仪所替代。选频式辐射测量仪可以进行实时频谱分析,实现对复杂电磁环境中不同频率辐射源项的场强贡献水平的准确测量,便于分频段监管。
For mobile electromagnetic environment around the base station monitoring, the current commonly used portable, easy to operate broadband integrated field strength meter. Broadband integrated field strength meter for electromagnetic environment monitoring, can only get the integrated electric field strength value of a space position, when the surrounding electromagnetic radiation source is more complex, it is not possible to accurately determine the main radiation source. Abroad, broadband integrated field strength meter has been gradually replaced by the election-frequency radiation measuring instrument. The frequency selective radiation measuring instrument can perform real-time spectrum analysis to accurately measure the contribution of field strengths of different frequency radiation source items in a complex electromagnetic environment, thereby facilitating sub-band supervision.
