遵照毛主席“要节约闹革命”的伟大教导,自己动手制成这一仪器。它与普通示波器配合可显示晶体管的共射极输出特性曲线族,且不影响示波器的正常使用状态。使用简便、直观,装制容易。基极电流为八级,每级电流最小为1μA,最大为100μA,共五挡。视被测管为NPN型或PNP型,仪器极性可正可负。集电极 In accordance with the great teaching of Chairman Mao “to save the revolution,” we made this instrument ourselves. It cooperates with the common oscilloscope to display the common-emitter output characteristic curve family of the transistor, and does not affect the normal use of the oscilloscope. Easy to use, intuitive, easy to install. The base current is eight levels, each current minimum is 1μA, the maximum is 100μA, a total of five blocks. Depending on whether the tube under test is NPN or PNP, the polarity of the instrument may be positive or negative. collector
