The best way to use AC sweep analysis is to set the source magnitude to one. This way, the measured output equals the gain, relative to the input source, at that output. Setting up an AC stimulus To run an AC sweep analysis, you need to place and connect one or more independent sources and then set the AC magnitude and phase for each source. Note: Unlike DC sweep, the AC Sweep/Noise dialog box does not include an input source option. Instead, each independent source in your circuit contains its own AC specification for magnitude and phase. To set up an AC stimulus 1. Place and connect one of these symbols in your schematic: Table 10-1 For voltage input Use this... When you are running... VAC An AC sweep analysis only.
