I can't imagine what they want a two tone signal for in alignment.
Maybe to set the alc level?

To do much else with it you also need a spectrum analyzer.

Automated Industrial Electronics had an option where you could tie two
of those boxes together and generate two tones at once if I remember
right. Pretty rare though.

They did also make a specific two tone generator box for ssb. They did
have a pretty good sine wave out. You probably won't see many around
though.
