Oscilloscope probe grounding
WebJul 19, 2013 · Oscilloscope users frequently need to take floating measurements in which neither point of the measurement is at ground potential. The signal common can be elevated to hundreds of volts from earth and, in addition, a number of these measurements must reject high common-mode signals. (A common-mode signal is a signal present at … WebMay 27, 2016 · When scopes measure voltages not referenced to ground. May 27, 2016 By David Herres 1 Comment.

WebIf you're measuring a grounded circuit, the path of the ground current involves the power cables on the device under test and the oscilloscope itself, and possibly a trip to your breaker panel and back too. That's one long unshielded cable run, and its adjacent to power wires too so will pick up all sorts of noise.
