How does an oscilloscope work?

February 14, 2025common problems 8320

An oscilloscope uses a probe to connect to a test point in a circuit and amplify or attenuate the voltage at that point. The subsequent signal path depends on the oscilloscope, but in general, analog circuits condition the signal and analog-to-digital converters digitize it for further evaluation, processing, and analysis.
