摘　　要：为提高瞬态响应测试仪的测量精度和响应速度,提出了一种基于现场可编程门阵列(FPGA)实现的设计方法.系统设计采用Xilinx公司生产的Xilinx Spartan 3E XC3S500E PQ208 FPGA作为控制核心,实现了对瞬态响应的峰值时间、超调量及调节时间的精确测量,并且能较准确地绘制二阶系统的瞬态响应曲线.系统显示模块采用VGA显示,既节约了IO口资源,又可以更加逼真地显示相应曲线.系统可通过模拟开关实现单脉冲信号的输出,并扩展了语音提示功能,使用更方便.实际测试表明,系统具有运行稳定、参数测量精度高、抗干扰强及响应速度快的优点.In order to improve the transient response tester measurement accuracy and speed of response, a design method is proposed based on FPGA implementation. The system design using the Xilinx company＇s Xilinx Spartan 3E XC3S500E PQ208 as the FPGA control core, achieves a precise measurement to the transient response of peak time, overshoot and settling time and can ac- curately draws the second transient response order curve of the system. The display module opt VGA display not only saves IO port resources ,but also more realistically displays the correspond- ing curve. The system can achieve the pulse signal output by a single analog switch and is easier to use the system expansion voice prompts. The practical tests show that the system has the advanta- ges of stablility, hi^h-parameter measurement accuracy, strong anti-interference and fast response.
