Look in the Spectrum Analyzer manual and see if it mentions a model of generator that can be cabled to it and used a slaved sweep generator. That will give you the functionality of a tracking generator. The go looking for that model number, perhaps on ebay, Twenty years ago I saw a rube goldgerg kluge of a 141T Spectrum Analyzer and a RF generator that made up a tracking generator system, and used to tune duplexers and front ends.
