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.
