If you want to specify multiple stimulus types If you want to run more than one analysis type, including a transient analysis, then you need to use either of the following: ■ time-based stimulus parts with AC and DC properties ■ VSRC or ISRC parts Using time-based stimulus parts with AC and DC properties The time-based stimulus parts that you can use to define a transient, DC, and/or AC input signal are listed below. In addition to the transient properties, each of these parts also has a DC and AC property. When you use one of these parts, you must define all of the transient properties. However, it is common to leave DC and/or AC undefined (blank). When you give them a value, the syntax you need to use is as follows. For the meaning of transient source properties, refer to the I/V (independent current and voltage source) device type syntax in the Analog Devices chapter in the online PSpice Reference Guide. This property... Has this syntax...
