Waveform reconstruction of nanosecond pulse measurement

In order to correct the effect of the atrociousness parameter of monitor on waveform, we made Fourier transform of the signals of source and monitor and got the function of monitor sensitivity and phase with frequency using the signal spectrum of source dividing the signal spectrum of monitor. In measurement, we made Fourier transform of the signal of monitor, multiplied by the function of monitor sensitivity and phase with frequency, then reconstructed the waveform with Fourier reverse transform. The method transforms the time domain signals into frequency domain signals, and then reconstructs the signal with a coefficient determined from calibration. Theoretically, the method can improve the monitor’s spectrum as the standard monitor. It is proved with experiment that this method can re
