The improvement of electronic paramagnet resonance (EPR) system was achieved by adding a self-made circuit of power amplifier ,a new data acquisition system and a high resolution gauss meter ,which were based on NI hardware and software .The measurement of EPR spectrum could be performed under conditions of simultaneously obtaining the values of EPR signal and the am-plitude of the magnetic field .The g factor and the FHMW line width of DPPH sample had been stud-ied and the result showed a high accuracy and precision .
