The situation of the test system of accelerometer is analyzed, testing system for accelerometer based on GPIB is designed, and the composition of the data acquisition system is ensured in terms of test principle. The performance analysis platform of accel-erometer has been constructed according to the relationship between its output and coefficient of static model equation. The method of test data acquisition and processing, and how to realize the storage and calling of the data through Access have been discussed in detail. Finally, with the help of MATLAB tool, the accelerometer's performance parameters model has been built, and the corre-sponding forecasting and differential evaluation has been done.
