Default Spice simulation and CISPR

Hello all,

I am quite new in this field and want to start by doing some comparison between simulation and measurements.
The measurements are done according the CISPR standard with 9kHz / 120kHz bandwith rate.
For the 9kHz range i get good results when I do the simulaiton with a simulation time of around 100us.
For the 120kHz I have problems, because my transients are quite slow and i can not stop the simulation at 1/120kHz, because then i would not have one cycle completed.
Is there a work around or a way to "resample" the simulation to a different bandwith???

Regards
