Multimeter & Oscilloscopes

Analogue Oscilloscope

An Analogue Oscilloscope is based on the movement of a light point over a cathode-ray tube screen in real time, this movement causes a light beam that remains temporarily on the screen as if it were tracing a line.

Therefore, its image cannot be displayed continuously as the trace moves from left to right on the screen.

The main problem of this type of oscilloscope lies in very low or high frequency signals, as when tracing in real-time the light beam is not displayed or is illegible.
