The method of magnetic measurement with the help of moving coils is the most important measurement method for particle accelerator magnets. Although this oldest of the currently used method have remained unchanged for a very long time, the electronic equipment and software have been subjects to continual development and improvement. Report describes a new set of specialized electronic modules intended for measurement with moving coil. This set includes Integrator with Digital Output (Digital Flux meter) and Low Noise Zero Drift preamplifier. The principles of operation and main characteristics of these devices are discussed. A few systems, based on described equipment, are built up during last two years. These systems used different coil configuration: rotating coils, flip-flop coils, stretched wire. Parameters of systems are reported. Finally, the description of software, developed for moving coil measuring systems is presented.

The Metrology Light Source (MLS), a specialized synchrotron radiation source (electron energy up to 600 MeV) being built at the PTB in Germany. The multipole magnets of the Storage Ring consist of 24 quadrupoles, 24 sextupoles and 4 octupoles manufactured by Budker INP. The quadrupole magnets of 165 mm length have gradient of 13 T/m and aperture of 70 mm. The sextupole magnets of 80 mm length have strength of 280 T/m2 and aperture of 76 mm. The octupole magnets of 80 mm length have strength of 2400 T/m3 and aperture of 86 mm. The main features of magnetic modeling and manufacture are described in the paper. The multipoles were magnetically measured by Rotating Coil System and main results of the magnetic measurements are also presented.
