For filter work, I think you probably want a "sweep generator", not a
"spectrum analyzer". Many of the elements are the same but a sweep
generator is a far less ambitious project that is probably what you
want for alignments and filter design.

I would think a good SA with a tracking generator would be
cat's meow.

Well, yeah, if you can swing it. But a sweep generator is more than
sufficient for filter design and alignments. And every decent radio/TV
repair shop had one already meaning they show up really really cheap
on E-bay or hamfests a lot. Or you can homebrew a sweep generator (see
EMRFD or a ARRL handbook) out of junk box parts for your particular
band of interest.
