  • 频谱分析仪和场强仪的区别
  • 本站编辑:建德市梅城高频电磁仪器厂发布日期：2019-04-11 20:55
场强仪与天线联系非常密切，假如请求一定的丈量精度那么从式就知它直接与天线增益Ga有关再则是天线的作业频率规模有关这是最起码的请求因此不能说随便找一根天线接在电平表上就行了。
频谱仪自身即是丈量频谱规模内的信号电平假如用“零跨导”则即是一个选频电平表。


The field strength is very closely linked to the antenna, If you request a certain measurement accuracy, then the slave formula knows that it is directly related to the antenna gain Ga, and then it is the operational frequency scale of the antenna. This is the minimum request so it can not be said that a simple antenna is connected to the meter.
The frequency spectrometer itself is the signal level within the spectrum scale measured. If "zero transconductivity" is used, it is a frequency spectrum meter.
