Oscilloscope Probes:Theory and Practice Peter D. Hiscocks, James Gaston Syscomp Electronic Design Limited July 12, 2007. 1 Introduction Measuring an electrical signal inevitably affects that signal. This applies to all mea- surements, including the display of an os- cilloscope waveform. Affecting the sig- nal cannot be totally eliminated, but it can be minimized sufficiently that the effect is unimportant. Then the measured result is a sufficiently accurate representation of the real signal. It is therefore critical for the measure- ment engineer to understand the effect of the instrument on the signal.
