In Capture, open CLIPPER.OPJ. 2. Select the DC voltage source, Vin, and press D to remove the part from the schematic page. 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 2-19. 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. Note: PSpice simulation 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. 8. Click Apply to update the changes and then close the spreadsheet.
