This paper introduces the hardware desigh of a portable measuring system in magnetic memory testing. According to the basic principles of MMT（Magnetic Memory Testing）, the portable magnetic memory detecting instrument based on the embedded configuration was developed. Based on Modular Design and S3C2440 A MPU, the hardware platform was designed and some effective measures was taken to reduce the influence of various main interference sources on the instrument. The system function complete, easy and convenient operation, easy to carry, conform to the requirements of the site inspection application.
