Oscilloscope high voltage differential active probes

A “differential” probe is an active probe which has two inputs, one positive and one negative as well as a separate ground lead and it drives a single terminated 50Ω cable to transmit its output to one oscilloscope channel. The output signal is proportional to the difference between the voltages appearing at the two inputs. A differential probe is used to look at signals that are referenced to each other instead of earth ground and to look at small signals in the presence of large DC offsets or other common mode signals such as power line noise.
