Design of Programmable Laser Receiver Signal Simulator

摘要

A rapid changeable signal should be provided for Laser receiver testing. To this meet requirement, this paper raised a design of Laser receiver Signal Simulator adopting DSP, FPGA and high precision DAC. The Signal Simulator can change output amplitude and frequency once per lms, provide different output wave combinations and give a smooth transition when two different waves connect. The design has a simple structure, strong anti-interference ability, overcomes the shortcoming of traditional signal generator, meets the excepted performance. This design has been applied to a real laser receiver's system for simulation and test.
