My budget is at/around US$320.

Perhaps an HP 8640B generator. I have several and used to fix them.
Looks like the selling price is about $300 (including shipping) on
eBay:

Hmmm... Might go slightly over your limit, but methinks is with it.

Also, I've been able to find rather old service monitors, which I
consider more useful. Wavetek or SSI 3000A. I think I paid about
$300.

Gotta run...
