WebMar 6, 2024 · Attenuation in an oscilloscope probe refers to the amount by which the input signal being collected with the probe is reduced. The effect of attenuation is to reduce the input signal level to a lower value. Oscilloscope probe manufacturers will generally supply a probe with their systems that offers selectable 1x or 10x attenuation.
