| Abstract: | In this paper, the hardware constitute and the design of controlling and analyzing program of a multi-channel high sampling and long record system data acquiring and analyzing are described. The synchronous data of current, electric field change, dE/dt and magnetic field et al with the order of microsecond are firstly acquired by using this system during artificially triggered lightning experiment carried in Pingliang country, Gansu on July 1997. Using this system, the measured lightning waveform can be analyzed and carried out multi signal deal. |
