Testing an Oscilloscope with Arduino

So someone gave me an oscilloscope, how can I test it and make sure it works?

I was thinking of using PWM, it that good to start with?

It's a reasonable start, but quite a low frequency, less than 500Hz

Just "use" it.

In what way do you want to "test" it?

Most scopes will include their own test facilities, like a square wave output at a fixed frequency for probe calibration, etc.

On an Arduino, with nothing special running, you could probe the 5V and 3.3V to see that the scope reads the right level. You could try probing the resonator to see if you can discern the right frequency.

And yes, you can generate some PWM signals to look at pretty square waves if you want :wink:

Well I want to see if its broken somehow or in good condition.

Trying PWM I see waves like below, am I going to see the vertical traces or not necessarily?

This is a commonly available and good basic tutorial on How To Use an Oscilloscope…
While written for Amateur Radio operators and rather fast moving it does cover the basics, Perhaps it might be of use to you.

Analog or digital 'scope? Digital scopes can draw in the verticals, but with analog rapid
changes are fainter because fewer electrons hit the screen per unit area.
