英文摘要：

This paper presents a pulse circuit using a subnanosecond discharge tube. Through calculation and test research, the amplitude, half-width and rise time of the pulse are given. The paper also gives the structure parameters and principle of selecting the elements of the circuit. The lab test indicates that the pulse signal it produces is steady, with wide spectrum and has good repeatability. The rise time of pulse signal is less than 500ps, half-width is less than 1 ns and amplitude is larger than 4KV. It can be used as the PD source in the study of propagation characteristic in the UHF PD measuring for power transformer and GIS.
