WebIntroduction. Oscilloscope users often need to make “floating” measurements where neither point of the measurement is at ground (earth) potential. “Signal common” may be elevated to hundreds of volts from earth. In addition, many of these measurements require the rejection of high commonmode signals 1 in order to evaluate low-level signals.
