%X A novel approach called high speed electro-optic gating system was introduced to obtain the high speed electrical modulation signal. The system consists of two modules: gating pulse module and high voltage modulation module. The gating pulse module includes high-speed signal amplifier, FPGA (Filed Programmable Gate Array) delayer and controllable delayed transmission-line. The integration of the significant control function into FPGA achieves a number of desired properties such as high density, high integrated, erasable, filed programmable, and modulation-flexible. The overall delay was separated into digital delay and analog delay, which were finished by FPGA and controllable delayed transmission-line respectively. Experiments show that the system can generate a high-voltage rectangular electrical pulse with repetition frequency 1 Hz to 1 kHz, stepping 1 Hz, delay range from 0 to 1 μs, stepping 1ns, high voltage range from 0 V to 8 000 V, rising edge and falling edge within 10ns, jitter within 1ns. It can be applied to various electro-optic equipments.
