I have a function generator and I noticed that its DC GND is internally wired to its earth pin.
Similarly I have an oscilloscope and I noticed that its DC GND is also internally wired to its earth pin.
So now If I use this function generator with this oscilloscope(with 3-prong power cords) wouldn't there be a ground loop?
If so, should I use 2-prong power cable for one of the instrument to eliminate it as a solution?
EDIT: An illustration for the question:
On the left side the box represents the function generator, on the right side the box represents the oscilloscope.
Circles represent the BNC connectors.
Number 1 and 3 are analog grounds of the function generator and the scope.
Number 2 is the GND shield of the coax cable, where the coax cable is connected from function generator to the scope (i.e. function generator and scope GND are connected)
Number 4 is the earth wire
L, N, E are the line, neutral and earth pin of the 3-prong power cable.
