I wonder if anyone knows of a project or kit that uses a 'scope

to make something that would be useful for filter work so I'm not
necessarily looking for very wide frequency sweep.

Hey OM
In the old analog TV days I used a cable ready varactor tuner as a
sweep generator to drive the scope and MAKE it a spectrum analyzer.
All you needed was a ramp voltage to sweep the varactor tuning with.
Nowadays I could use a transceiver hooked up to a computer and use
digipan or ham radio deluxe to do that.
