The sine wave signal excitation source of meeting the requirements of ACFM was designed. This circuit are composed of direct digital synthesizer, low-pass filters, programmable amplifier and power amplifier. The design idea overcame the shortage that frequency and voltage were uncontrollable in the ACFM traditional detection systems before. It proved that the circuit can realize the objective as follows: the excitation’s frequency and voltage are stable and controllable; The output current is strong enough; The signal to noise ratio is high enough. This design are completely satisfied to the ACFM system’ requirement
