3 From the Place menu, choose Part.
4 In the Part text box, type
VAC (from the PSpice library
SOURCE.OLB) and click OK.
5 Place the AC voltage source on the schematic page, as
shown in Figure 17.
6 Double-click the VAC part (0V) to display the Parts
spreadsheet.
7 Change the Reference cell to Vin and change the
ACMAG cell to 1V
.
8 Click Apply to update the changes and then close the
spreadsheet.
To set up and run the AC sweep simulation
1 From Capture’s PSpice menu, choose New Simulation
Profile.
2 In the Name text box, enter AC Sweep, then click
create.
The Simulation Settings dialog box appears.
3 Click the Analysis tab.
4 From the Analysis type list, select AC Sweep/Noise
and enter the settings shown in Figure 19.

Note PSpice simu
l
ation is not
case-sensitive, so both M and m can be used
as “milli,” and MEG, Meg, and meg can all
be used for “mega.” However, waveform
analysis treats M and m as mega and milli,
respectively.
