Pls what are d usefulness of an oscilloscope

An oscilloscope enables u to view electronic signal waveforms as they occur. modern oscilloscopes allow u to save waveforms for future analysis.

While troubleshooting, or designing, electronic systems that incorporate a microcontroller, or even just an oscillator, u will often need to view their signals to analyze and assess them. The oscilloscope presents this as a waveform for u to view.
This way, u could locate any glitch, transient or electrical noise.
Take a look at the link below. There are pictures of my own oscilloscope in use. And the descriptions too. That should help u.

I am presently offering to order some oscilloscopes. Please view this link and contact me if interested.
