What is the peak-to-peak voltage level below which signals may be difficult to see using a 10X oscilloscope probe?

The peak-to-peak voltage level of 10 mV is significant because, at this low voltage threshold, the signal may be obscured by noise inherent in many electronic systems and in the environment. A 10X oscilloscope probe has a certain amount of sensitivity and attenuation characteristics, which means that when measuring very low signals, there may not be enough signal-to-noise ratio for the oscilloscope to display a clear and accurate waveform.

At 10 mV, the oscilloscope might struggle to differentiate the actual signal from background noise, resulting in a display that could appear noisy or even unusable. As the voltage level increases, such as to 20 mV or higher, the ability to visualize the waveform improves significantly because the signal rises above the typical noise floor, making it easier to identify and analyze the signal's characteristics.

This context helps in understanding the limitations imposed by the equipment at lower voltage levels, particularly with respect to oscilloscope probes and their corresponding ranges of visibility for signals.
