A new teaching platform for nuclear electronics experiment was introduced.The platform is designed with high speed circuit design and digital reconfigurable technology. New experimental contents and testing methods are introduced based on traditional experiments. Test shows that the front-end circuit can gain 0 to 10 times within the output linear dynamic range of ± 2.98 V, and the resolution of the digital MCA combined is improved by 30.39% relatively with digital filter. The 10 hours stability test shows that the peak position of the digital multi-channel system floats within the range of 0.43% around 625.69,and the resolution floats within the range of 0.55% around 10.97%, and the baseline remains the same level. The platform has been put into use.%介绍了新型核电子学教学实验平台的设计.平台的设计采用高速电路设计和数字可重构技术,在原有实验的基础上引入新的实验内容和测试手段.性能测试表明:前端电路增益可以在输出线性动态范围为±2.98 V 内实现0~10倍线性可调,其中2倍和10倍增益的3 dB带宽分别大于350 MHz和280 MHz;数字成形技术使数字多道的分辨率相对提高了30.39%;10小时稳定性测试显示数字多道系统的峰位在625.69上下0.43%范围内浮动,分辨率在10.97%上下0.55%范围内浮动,基线基本保持不变.实验平台已经通过测试并应用于教学实验中.
