Adding two PAC sources with differnt frequency range/ sweep for a PAC analysis

RFStuff

Dear All,

I want to excite a LPTV system with two PAC sources with separate frequency range.

For example:-

I have an LO frequency "Fc". PSS has been done with Beat frequency of "Fc".

Now I want to do a PAC simulation with frequency sweep from "Fc-Fm1" to "Fc+Fm1".

I also want two PAC sources such that during sweep one source will have a sweep of "Fc+Fm1" to "Fc-Fm1 and other source will have a sweep of "Fc-Fm1" to "Fc+Fm1".

Is it possible to archive that in spectre.

Please let me know.

Kind Regards,

    You can't do this. You can have multiple sources, but they will all be set to the same frequency at the same time - you can't have them sweeping in opposite directions.

    Regards,

    Andrew.
