Design of a 1.2 GSPS single-channel real-time long-distance transmission sampling system for fast-transient signal

    Corresponding author: CHENG Xiao-Lei,

Abstract: This article has introduced the origin and speciality of fast-transient signal, and told the meaning of researching on fast-transient signal. The main troubles of sampling on fast-transient signal is its `fast' and `transient', and the experiment's bad condition also troubles the transmission of information. To solve those troubles we put forward a technology called `digital Forward-sampling', and designs a sampling system for the fast-transient signal with this technology. The sampling rate of this system is 1.2 GSPS; it could get the whole pulse of fast-transient signal through the digital Forward-sampling technology; this system also could transmit the result to the analyzing equipment kilometers away immediately, before the data was destroyed by the electromagnetic and
mechanical wave. In the end, this article tells the result of testing on this system, and gives the improved project.
