[Boatanchors] "Sweep" techniques

Hello to all. I've been a ham for a long time and there is one area where not only is my knowledge severely lacking, but I seem to be unable to find any decent info on this technique.

The subject is 'sweep alignment' of IFs and filters, etc.
I have quite a few Tek 'scopes, and also a nice collection of MODERN Sweep/Function Generators. Krohn-Hite, Exact, etc. I have also purchased and repaired a ton of test equipment including 'scopes and TDRs, in addition to my boatanchor collection.
The manuals for the Sweepers assume you know how to connect them and use them.

A while back, I noticed that there were several articles in ER Magazine showing the swept response of various boatanchors, (SX-117, etc). Unfortunately, the authors never describe the test methodology. I have purchased more than a few (!!) "How to use your Sweep/Signal Generator" books.
However, they are pretty old and only deal with old, tube type TVs.
I even suggested to Ray at ER Mag that this subject would make a great article and he agreed, but I still haven't seen anything.

So, could some of you guys with all the expertise in this area (Carl, Al) at least give me a shove in the right direction?

Yes, I have searched the WWW extensively and no joy......

Thank you!
