Abstract— A the high-voltage divider for pulsed signals was developed for multichannel DAQ-system of the LIA-20 linear induction accelerator. The divider satisfies a range of requirements: a range of operating voltages up to 30 kV, a 30 MHz bandwidth, accuracy and stability characteristics that are better than 1%, and repeatability of its parameters during mass production. An analysis of various variants of high-voltage dividers is given: passive capacitive dividers and capacitive dividers with active components, as well as resistive, resistive-capacitive, and combined dividers. The configuration selection of the divider circuit with the necessary properties is substantiated based on the analysis.
