Tool/software:
1) While simulating FPD-III , I setup a simulation sweep from 0 to 2.1 GHz for example and make a snp file from it.
2) Now, if I send a FPD-III signal of 4.2Gbps (2 x 2.1GHz) through this snp, will it be fine to get fairly accurate results in terms of Eye diagram etc. or I need to run the simulation sweep from 0 to 4.2 GHz instead
