【Abstract】 Designing and implementing a general signal simulator are discussed in this paper, in the simulator, data transmitting between computer and outer instrument based on EPP parallel port. This paper introduce a general signal simulator which based on memories and discusses the application of Programmable Logical Devices(PLD) in this simulator. Adopting method of combining software and hardware, simulator simulates the output video signal of the terminal of radar receiver. By inputting different data through it can be used to adjust and test radar signal receiver and reach different test requirement. The instrument can be used conveniently and it has strong adaptability and its cost is low, you can change or extend its function with various requirements.更多还原
