Hi Zheng,

probably you want to simulate the frequency response of your filter. In this case I suggest you the analysis PSS and PAC which are the steady-state and AC analysis for a periodic circuit (like SC-filters).
The circuit should be fed with a PAC signal (you can use "vsource" or "port" in "analogLib") and the output voltage can be plotted from ADE with Result-> DirectPlot-> MainForm.
If you are not interested to the sidebands of the (sampled) output signal the "maximum sidebands" in PSS analysis and "harmonics" in PSS should be both set at 0 (base-band).

Bye,
Cri
