Developing with the research on ICF, more and more attention is paid to the high power laser power conditioning system. In order to obtain accurate experiment data for researching on transmission efficiency of the high power laser power conditioning system, the structure of the controlling, measuring system and its real time measure method for the characteristic data during the instantaneous discharging process of the xenon flash lamp were presented. A quantified transmit model was adopted to measure and transmit the characteristic data, and it realized not only separating high voltage, but also preventing from being disturbed during long distance transmission to ensure measuring precision. Cooperating to the modularize design of the system, the control function was divided into several threads to enhance the ability of real time and harmony, and it realized the remote controlling high power system by low one effectively. The results show that the precision of the system is satisfied with the requirement of analysis and now the system is applied in experiment and research on power conditioning system.
