Time constants, the start time, stop time and maximum time step. Like the measure command, the transient command starts with a period, "." then the work "tran" followed by a series of In order to view this curve you need to know two commands, the transient command and the initial condition command.Īn explanation of these two commands now follows. When power is applied to a capacitor the voltage will rise exponentially and this is a good curve to view in LTSpice. See the previous page onĭrawing the Schematic if you have trouble. In this circuit the DC voltage source is set to 10 Vdc. Like the resistor,capacitor, inductor and ground symbol can be selected from the top menu line. The F2 key will give access to all the components in LTSpice, frequently used parts Either from theĮdit menu, or by pressing F2. Start LTspice and select New Schematic from the File Menu. You must know something about the signal to set-up the correct parameters for a transientĪnalysis. This mode of analysis is very similar to viewingĪ waveform on an oscilloscope. Transient analysis allows you to view signals in the time domain.
