Signal generators - and similar items of T & M kit: it's always handy to have more than one of any given instrument. That way, when you've made a measurement and think "Huh? That can't be right!" you can then repeat same measurement with the other one(s) available. Chances are that both will give the same result - so the trouble doesn't lie with the instruments. But with only one instrument, the doubt will be there, leading to all sorts of blind alleys and probable unnecessary investigations.
As I've said many times, all our work with electronics is done with trust: trust in the reliability of your test kit, trust in your correct use of it, trust in your ability to make sense of what it tells you. And if that trust is ever in doubt . . . .
