Why are the Outputs of many function generators earth grounded?
As far as I understand grounding the generator or Parts like the chassis can reduce shock hazards if something fails within the generator.
But it also produces ground loops when I try to measure things with my osci.
Ok but why are the BNC Outputs also ground referenced? Cant I simply cut the ground wires from the Outputs to ground so the Chassis is still earth grounded but my outputs are not to get rid of my ground loops? Or does this have any effect I am Not seeing?
update:
Thank you all for your replies. What I did not understand was: the gnd wire is also connected to ne neutral wire in the transformer.
I really did Not get how a current could actually Flow if I only have the signal wire (inner BNC) and only gnd aa the outer shell.
