Hi,
Is it possible to use SpectraSys to model direct conversion systems (Zero IF)? Actually, can SpectraSys understand Complex Baseband signals at all?
I have tried but I seem to fail how to configure the mixers. In a TX test setup I have two sources with 0/90 deg phase shift and have entered a reference clock name to make sure they are "synched". My LO's are 90 deg apart (of course). Still I get only like 15 dB image reject.
Our company is evaluating Spectrasys but maybe it is not the tool we should use for this?
Kindly, CG
