The traditional measure method of the power withstand test is to use the voltage meter, ammeter, power analyzer, frequencyanalyzer etc to measure the waveform and parameters of the power signals.
传统的工频耐压试验是通过电压表，电流表，功率分析仪，频谱分析仪等等来分别测量波形及其各个参数的。

Modulation Domain and Pulse Analyzer(MDPA) analyzes signal using a plane domain which is consisted of frequency and time.
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。

The essential difference is that the spectrum analyzer, being designed for laboratory use, is designed to cover an extremely wide frequency range with widely adjustable tuning range, bandwidth, etc.
