This is how I do it with my BPF:
1. On schematic put voltage source on the input and set PAC magnitude to 1. Do not forget to put clock source.
2. In ADE choose PSS and set parameters
- clock is from shematic - set fundamental to auto calculate
- number of harmonics 0
- tstab to what you need
3. In ADE choose PAC and set parameters:
- PSS beat freq should be set automatically
- start, stop and others like for AC
- maximum side bands 0
Start the simulation.
