摘　　要：常用的信号源与示波器存在体积大、成本高、携带不便等问题,难以满足学生的课外实验所需。为了丰富学生的第二课堂,提高学生的动手实践能力,设计了一种基于FPGA的便携式课外实验仪。该实验仪具有信号源与示波器的功能,信号源可以产生正弦波、三角波和方波。经过实验测试表明,该设计成本低,可靠性强,参数精度高,方便实用,能够满足学生课外实验所需。In second classroom of the electronic experiment and training for the electrical engineering students, it is hard to meet the students＇ requirement because of the large volume, high cost and inconvenient to carry the signal source and the oscilloscope. In order to enrich the students＇ second classroom and improve their practical ability, based on FPGA （Field Programmable Gate Array）, a portable extracurricular experiment apparatus was designed. The experimental apparatus can combine the function of signal source and the oscilloscope. The signal generator can generate the sine wave, triangular wave and square wave. The experimental tests show that the design has the characteristics such as low cost, high reliability, high data precision, convenience and practicality. It can meet the requirement of the student＇s extracurricular experiments.
