There is a specific sweeper circuit for viewing IF curves on a scope was
 called a "Wobbulator"  the British vintage radio magazine "Radio Bygones'
No. 82 April/May 2003"   featured a updated advanced model - If you search
for it - you will find a copy of it on the net.

A UK glowbug that goes by the moniker "AndyDaviesByTheSea" on You Tube has
a nice demonstration of the unit in action - he credit the
units usefulness in one of video in getting a grossly misaligned  Eddystone
communications receiver  back on track.   Try Videos   44- 48
