Measurement Considerations
Model 2750 Multimeter/Switch System User’s Manual
shows how to connect several instruments together to eliminate this type of
ground loop problem. Here, only one instrument is connected to power line ground.
Ground loops are not normally a problem with instruments like the Model 2750 that have
isolated LO terminals. However, all instruments in the test setup may not be designed in
this manner. When in doubt, consult the manual for all instrumentation in the test setup.
