In this paper, the bounded-wave EMP (electromagnetic pulse) simulator, electromagnetic pulse simulator as an external high-energy pulse excitation source for the prediction of complex electromagnetic environment of the experimental study of electromagnetic necessary technical support. Designed on the basis of learning simulators principle and structure of a small parallel-plate EMP simulator space field measurement system. The system consists of the electric field measurement probe, signal conditioning circuits, high speed data acquisition part. Which high-speed data acquisition part the Canadian AlazarTech's high-speed data acquisition card ATS9350.

Access to a lot of literature on the basis of a variety of field measurement system program are reviewed and compared. Conducted a preliminary inquiry and analysis of the composition of the electromagnetic pulse simulator and its pulse source.

This design using OrCAD / MATLAB software to draw a signal conditioning circuit schematic and simulation from electric field probe sensor pulse power spaces voltage pulse signal carried the excitation source design, and with this incentive source schematic carried the MATLAB simulation validation, have a desired signal conditioning results.
