A new harmonic coil measurement system based on a dynamic signal acquisition device has been successfully developed to check the field quality of the quadrupole magnet for the CSNS/RCS which operates at the 25 Hz excitation cycle with a DC bias It was designed to acquire multiple channels of data with a wide dynamic range of input signals which are typically generated by a harmonic coil and an encoder A dedicated algorithm was developed in LabView code to identify over specified intervals synchronized to the coil s rotation in the magnetic field Through full integration of hardware and software
