In the Analysis Setup dialog box, click Transient to display
the Transient Analysis dialog box.

Clear the DC Sweep check box to disable the DC sweep
from the previous example.
DC Sweep is disabled here so you can see the results of a
transient analysis run by itself. PSpice A/D can run multiple
analyses during simulation (for example, both DC sweep
and transient analyses).

From the Analysis menu, select Simulate.
PSpice A/D uses its own internal time steps for
computation. The internal time step is adjusted according to
the requirements of the transient analysis as it proceeds.
PSpice A/D saves data to the Probe data file for each
internal time step.
Note
The internal time step is different from the Print
Step value. Print Step controls how often optional
text format data is written to the simulation output
file (.
