Abstract
The accurate measurement of fast rise time EMP is critical. The loss and dispersion characteristics of signal measurement cables cause distortion in these measurements. To compensate for a distorted pulse, an appropriate compensation method is essential. Ordinary methods are not accurate, and the FFT calculation method requires a great deal of computer resources. An analytic derivate equation using Cauchy's theorem shows good results which have been proved by comparing the equation's results with real world pulse measurements.
