DC sweep analysis
You can visually verify the DC response of the clipper by
performing a DC sweep of the input voltage source and
displaying the waveform results in the Probe window in
PSpice. This example sets up DC sweep analysis
parameters to sweep Vin from -10 to 15 volts in 1 volt
increments.
Setting up and running a DC sweep analysis
To set up and run a DC sweep analysis
1 In Capture, from the PSpice menu, choose
New Simulation Profile.
The New Simulation dialog box appears.
2 In the Name text box, type
DC Sweep.
3 From the Inherit From list, select Schematic1-Bias,
then click Create.
The Simulation Settings dialog box appears.
4 Click the Analysis tab.
5 From the Analysis type list, select DC Sweep and enter
the values shown in Figure 6.
