What does the Z axis on an oscilloscope represent?

The Z axis on an oscilloscope represents intensity or brightness of the trace displayed on the screen. This feature is crucial for differentiating between multiple signals that may be displayed on the same screen. By manipulating the intensity on the Z axis, a technician can emphasize certain waveforms or signals, making it easier to analyze their behavior or interactions.

This capability allows for more effective visual analysis of complex signals, as it helps in distinguishing overlapping traces by adjusting their brightness, thereby enhancing the visualization of important data. Understanding the function of the Z axis is essential when working with oscilloscopes in various applications, allowing for a more effective interpretation of the signal characteristics.
