A 20MHz oscilloscope is a basic electronic measurement instrument capable of displaying and analysing signals up to 20 million cycles per second.

Oscilloscopes measures voltage over time and allows you to visualise and analyse the electrical signals in a circuit. The oscilloscope displays these signals as waveforms on its screen, showing how the voltage of the signal changes over time.

Why would you use a 20MHz Oscilloscope?

• Basic electronics troubleshooting - checking for signal integrity, voltage levels, and waveform shapes
• Audio signal analysis - examining audio frequencies and waveforms.
• Education - teaching fundamental electronics concepts.
• Hobbyist projects - debugging electronic circuits.

While a 20MHz oscilloscope is a good starting point for many applications, it might not be suitable for high-frequency circuits or complex signal analysis. For those tasks, higher bandwidth oscilloscopes are required.
