The Design and Implementation of a Multifunctional Programmable Signal Generator

Abstract:

Signal source with high precision and programmable is needed in modern scientific research, communication system, teaching apparatus, electronic measurement and so on. In the paper, a portable signal generator is proposed, which has a core of AT89C51 and programmable DDS integrated chip AD9833. The paper also introduces the principle and implementation of system project. The generator can output sinusoidal wave, square wave, triangle wave, dc voltage, and it has manual and SPC two working mode, can implement PC SPC output through RS232 communication interface. Experiments show that the system has advantages of high precision, wide scope, small size and flexible operation etc.
