Hi.
What is your definition of SNR in TX ?
If you are thinking of non-modulated signal, SNR you should evaluate is C/N or C/N0. Here you have to consider bandwidth or offset frequency.
For modulated signal, SNR you should see is ACPR. And you have to see noise floor for out of band region. This out of band noise floor level is important for CDMA system. I make level diagram for TX which plot cascaded ACPR anf noise floor level, here I need P1dB(IP3) and NF of each stages. You are thinking of this out of band noise floor ?
Higher order harmonics, images of DAC, Local Leakage, etc. are treated as spurious.
