An oscilloscope is used to measure two key aspects:
- Voltage
- Time (and often, frequency with time)
A beam of electrons is directed across a phosphorescent screen horizontally (in the X direction) at a steady rate, typically one sweep per millisecond. An input signal adjusts the vertical position of the beam, affecting the Y axis. The resulting trace on the screen allows for measuring the voltage of the signal (from the Y axis) and determining the duration or frequency (from the X axis).
