A 100 MHz analogue oscilloscope is a type of electronic test and measurement instrument used for visualising and analysing electrical signals in the analogue domain.

The 100 MHz refers to the bandwidth of the oscilloscope. Bandwidth is a measure of the range of frequencies that the oscilloscope can accurately display. A 100 MHz oscilloscope can accurately display signals with frequencies up to 100 million hertz (100 MHz). This means it is suitable for measuring and analysing signals with frequencies up to this limit.

An analogue oscilloscope uses analogue components like cathode-ray tubes (CRTs) to display waveforms. It provides a continuous display of voltage over time, which can be especially useful for observing fast-changing signals and for visualising analogue waveforms. Analog oscilloscopes are less common today, as digital oscilloscopes have become more prevalent, but they are still used in some applications where their unique characteristics are advantageous.

What are 100 MHz analogue oscilloscopes used for?

They are used in various industries and applications, including:

• Electronics and Electrical Engineering for debugging, testing, and analysing electronic circuits and signals, especially for analogue circuit design and troubleshooting.
• Research and Development to study and evaluate analogue phenomena, signals, and waveforms.
• Education for teaching students about analogue electronics, signal analysis, and waveform visualisation.
• Sometimes used in audio and music production to visualise audio waveforms and diagnose audio equipment issues.
• In automotive diagnostics to help analyse sensor signals, ignition systems, and various analogue electrical systems.
