Research on calibration methods for pulse resistive divider

There are two methods commonly used for the performance test of voltage divider system. Step response method is used to measure the transient response of system, and frequency response method is used to measure the amplitude-frequency characteristics and phase-frequency characteristics. This paper discusses the equivalent conversion relationship of the characteristic parameters of time-domain and frequency-domain. On this basis, the calibration of pulse resistor divider has been studied. Comparative experiment results show these calibration methods have good accuracy and consistency. The frequency range of divider can be achieved from the time-domain response curves, and self-calibration can be accomplished.
