What is the vertical axis of an oscilloscope display also known as?

The vertical axis of an oscilloscope display is known as the Y axis because it represents the amplitude of the signal being measured. This axis displays the voltage levels of the waveform, allowing the user to analyze how the signal's amplitude varies over time. Understanding the relationship between the Y axis and the signal's voltage is crucial for interpreting the characteristics of the waveform, such as peak voltage and signal strength.

In contrast, the X axis typically represents time, illustrating how the signal changes over a specified duration, while terms like Z axis and T axis are not standard in the context of basic oscilloscope functions. The emphasis on the Y axis is fundamental in electronics, as it directly relates to measuring and analyzing voltage levels within circuits.
