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. I wonder how a flat noise source would work
in lieu of the TG to plot filter responses on a SA?
