Using Sinusoidal Inputs in PSPICE

ECE 240 Electrical Engineering Fundamentals PSPICE Tutorial #9 Using Sinusoidal Inputs in PSPICE In this tutorial, we will review the use of PSPICE to simulate a circuit with a Sinusoidal input . Figure 1 shows the PSPICE schematic for a circuit that was analyzed in class. The original circuit had a Sinusoidal input 9 cos 2t. Note the use of the VSIN source for this input . The VOFF is set to zero. The VAMPL is set to 9. The FREQ is set to the frequency in Hz. For this source the frequency in Hz is 2/(2 ) = 1/ = Figure 1. PSPICE Schematic Probes are placed in the circuit to measure the voltage across the resistor and the current through the inductor. Since we want to plot the voltage and current versus time, the Transient analysis is used. The Simulation Settings are shown in Figure 2. Note that the period of the input waveform is approximately 3 seconds. Thus, TSTOP was set to 9 seconds to provide a display of approximately 3 cycles.

Probes are placed in the circuit to measure the voltage across the resistor and the current through the inductor. Since we want to plot the voltage and current versus time, the Transient analysis is used. The Simulation Settings are shown in Figure 2. ... In this case PSPICE will let the circuit run to steady state BEFORE producing the plot.
