The measurement of the high voltage and narrow pule is very important in the field of automatic detection. The pulse devider combining the AD acquisition card is commonly used in a major component of the measurement system. Resistor divider is widely used because of its simple structure, excellent performance and easy operation. This article discusses the impact of the stray capacitance of the resistor divider of its performance, the introduction of the concept of the transfer function make the theoretical analysis more resonable, and introduces inductance compensation on this basis. The experimental results according to the theoretical results verifies the feasibility of the inductance compensation.
