Hi, everyone!
I'm designing one mixer which is low-IF architecture, (RF is 1575M, Lo is 1571M, so IF is 4M)
when simmulation with PSS or PSP, the Bit Frequency is 1M, if I want to observe 1.575G frequency or above, the sideband will be set more than 1500!
It's too big than the maximum sideband,250.
what's more, the sideband is big, the simulation is very slow!
who can tell me how to deal with this problem? thanks a lot

use qpss
also in pss u can choose which harmonics to save rather than all 1500
