Abstract
This paper presents the VsDC2 and VsDC3 multifunctional integrators developed at the Budker Institute of Nuclear Physics, Siberian Branch, Russian Academy of Sciences for measurements of both constant and pulsed magnetic fields. These integrators are based on the digital integration method which provides an error smaller than 10–5 for a wide class of measurements. The method used in the developed devices allows accurate synchronization of an integration interval with pulsed signals, while the ADC used in the measuring channel is clocked by an asynchronous and low clock frequency. The theoretical aspects of the proposed solutions are considered and compared with known methods of constructing digital integrators. The circuitry of these devices is briefly described, and the main characteristics are given.
