频率分析仪是一款分析频率的设备。
频谱分析法是用频率分析仪测量各次谐波的方法计算出波形失真度，但采用此种方法的仪器价格较昂贵。
The method of analysis frequency table is using the meter of frequency table to test all kinds of frequency and then calculate the distortion of the wave.
调制域及脉冲分析仪利用时间和频率构成的平面域对信号进行分析。
Modulation Domain and Pulse Analyzer(MDPA) analyzes signal using a plane domain which is consisted of frequency and time.
当信号从原中心频率偏移，信号越来越从设定的发射通道偏移，功率分析仪的功率电平会越来越低。
As the signal is shifted from the original center frequency, the RF power analyzer reads lower and lower power levels as more and more of the signal shifts out of the intended transmission channel.
