基于通用示波器的双簇型晶体三极管输出特性图示电路

内容简介：用矩形波发生器、锯齿波发生器、二-十进制计数器、阶梯波发生器、模拟开关、差分放大器、反相比例求和电路构成的双簇型晶体三极管输出特性图示电路，与通用示波器相结合能够实现两只三极管输出特性的同时测试，通过测试可以方便地比较两只三极管输出特性的异同。在缺少专用测试设备的条件下，采用上述方法对双三极管输出特性的异同进行测试仍是一种方便、实用的方法。

Abstract：The simultaneous test on two transistors output characteristics could be realized by combination of the general oscilloscope and the two transistors output characteristics graphic circuit composed of rectangle wave generator, sawtooth wave generator, the binary-decimal counter, ladder waveform generator, analog switch, differential amplifiers and umming amplifier, by which can conveniently compare the similarities and differences between two transistors output characteristics. Under the conditions of lack of special testing equipments, adopting this method is also a convenient and practical way to test the the similarities and differences between two transistors output characteristics.
