(四)转移特性共发射极组态的电流转移特性定义为集电极电压恒定时,集电极电流与基极电流之间的关系曲线.显示原理方框图见图10.锯齿电压经大电阻R_(62)变成锯齿电流加到被测管的基极,集电极电流由串入发射极电路中的电阻R_(68)上取得.转移特性亦采用单条显示.被测管集电极电压由电位器W_2改变,电压
(D) transfer characteristics Common emitter configuration of the current transfer characteristics of the collector voltage is defined as constant, the collector current and the base current curve between the display principle block diagram shown in Figure 10. Zigzag voltage by a large resistance R_ (62 ) Into a sawtooth current added to the base of the tube under test, the collector current by the string into the emitter resistor R_ (68) obtained on the transfer characteristics also used a single display tube voltage to be measured by the potentiometer W_2 Change, voltage
