     Yep.
     Sometimes/commonly there is ALSO a 'ramp' output that
     is an analog of the frequency.  Using that ramp to drive
     the horizontal input of the 'scope, so a 'poor man's
     spectrum analyzer' results.

     Not 'top drawer', but can be useful, instructive.

     One useful thing, at least to me, was to quickly look for
     multiple resonances.  May or may not show up, depending on
     frequency range....
