If I have a conventional superhet with an IF of 465 kHz and I wish to check the alignment of the complete IF amplifier using the 'wobbulator' technique - a ramp-modulated FM signal with the ramp synchronised to the 'scope timebase - what is a sensible range of sweep times / frequencies to choose for this task? And if I am examining only one IF stage, what times / freqs. should I choose for that exercise?

Thanks for your thoughts.
