英文摘要：

The frequency generating technique of a slip pulse generator for testing MCA is introduced in this paper. FPGA＆DDS is adopted to generate high precision signals. The design and implementation technology of hardware and software are illustrated. Tests show that the frequency rang of the generator is 5 Hz-20 MHz and the error is within ±0.1%. The achievements could be applied in related signal processing area.
