I bought an old Heathkit IG-42 "Laboratory Generator" at a flea
market
the other day. It powers up OK but I don't have anything to test it
with except a TEK 465 O-scope. I looked for an output with the scope
but couldn't find anything. I know the scope is working because its
1K hz calibration signal looks fine.

The generator dial goes from 100 KC to 30 MC. Is this too high a
frequency to be monitored with a 465?
