LTspice电子线路模拟教程 - 图文

垂直轴变了.0到.1.5V.

3.8.

求曲线上的值.你可点曲线名.出现虚白交叉线.中点为所求的值.

你还可再你可点曲线名选第二条虚白交叉线

从俩虚白交叉线可看出数据的差异.

3.8一般来说压是对地.如果你想知某元件两端的电压差该如何呢. 设一参考点.先点小人.然后在电路图的.空白处点右键.找黑白电笔.Set probe reference.也可从VIEW找.

按键盘上ESC可去黑白电笔.

3.8. Current Measurements

Make the circuit diagram window active.(...by a left mouseclick on it....) and move the cursor exactly over thecomponent of which you want to know the current. The cursor changes to a \mouseclick on the component you will see the trace current displayed in the waveform viewer..

Example:

Current in resistor R1 (Collector resistor of the left transistor, Q2):
