Kultus,,
there are two possibilities:
- function-generator ( 50Hz) run with battery-supply - then this is the
negative terminal of the batterie or midpoint of symetric battery-supply
Therefore all oszillators are free-wheeling ( no ground-reference )
- function-generator run by mains then it must be ground-reference.
ossillators have ground-reference
The first option is best because if you have this setup encased in a metal-box and leave the box not connected to ground it will not matter if by accident one wire hits the metal-casing.
