So one should not connect any two chassis of instruments if all chassis of instruments are grounded.
But we find that the GPIB cable shield also connect the chassis ground of all instruments we need to remote.
Should we disconnect the ground of the power cord to avoid such kind of goround loop?
P.S. The attached - shows what ground loop I mean.

But where is the measurement being made. I would expect from HI to LO.
If that is the case then a ground loops from GPIB cables would not affect the measurement.
