Technical Note Differential Oscilloscope Measurements A Primer on Differential Measurements, Types of Amplifiers, Applications, and Avoiding Common Errors introduction of solid-state gain circuits, high perfor- mance voltmeters could be isolated from ground, allow- ing floating measurements to be made. Most oscilloscopes today, like the venerable VTVM, can only measure voltages that are referenced to earth ground, which is connected to the scope chassis. These are referred to as "single- ended" measurements
