	The induction method of magnetic measurement is the most important, widely used and oldest measurement method for particle accelerator magnets. Nevertheless, both the new demands of the accelerator techniques and possibilities of modern electronics stimulate the creation of more accurate and fast instrumentation, based on the induction method. This report describes the multimode integrators intended for magnetic measurements with the relative accuracy better than 10^-4 and even better than 10^-5 in special cases. Integrators provide high accuracy level both for the constant magnetic field measurements using movable coils and for the pulse measurements also. Modern digital techniques are used to get the partial integral of signal in the strongly determined time interval. The paper considers theoretical issues of the digital integration technique and related error sources. The structure of digital integrator is presented, and key features are listed. In conclusion a brief description of two magnetic measurement systems is given. The first system is used to measure the magnetic field transverse distribution in pulse elements, and the second one – to measure the harmonics in magnetic lenses with constant field.

The induction method of magnetic measurement is the most important, widely used and oldest measurement method for particle accelerator magnets. Nevertheless, both the new demands of the accelerator techniques and possibilities of modern electronics stimulate the creation of more accurate and fast instrumentation, based on the induction method. This report describes the multimode integrators intended for magnetic measurements with the relative accuracy better than 10^-4 and even better than 10^-5 in special cases. Integrators provide high accuracy level both for the constant magnetic field measurements using movable coils and for the pulse measurements also. Modern digital techniques are used to get the partial integral of signal in the strongly determined time interval. The paper considers theoretical issues of the digital integration technique and related error sources. The structure of digital integrator is presented, and key features are listed. In conclusion a brief description of two magnetic measurement systems is given. The first system is used to measure the magnetic field transverse distribution in pulse elements, and the second one – to measure the harmonics in magnetic lenses with constant field.
