Ixon the difficulty / extra effort with using a SA + TG as a poor man's 
VNA is in calibrating out your cables + instrument.  If you are looking 
primarily for things like resonances and don't need to get the S 
parameters dead on, or you have the time and patience to compensate your 
measured results with post processing then the SA + TG can provide you 
useful insights.  If you need high accuracy, I would rent a VNA.
