Analog Oscilloscope
Is a measurement apparatus capable of visually depicting regular changes in electrical activity, such as an electrical current or signal. The resulting data appears as a waveform drawn on a graph with two axes, where the horizontal X axis represents time and the vertical Y axis indicates voltage. In addition, the luminance of the waveform itself is often referred to as the Z axis, which demonstrates the intensity of the activity measured.
