One more thing.
I have never seen colored oscilloscope screen like this.
Is it real?
If yes, how to infer the colors?

There are a lot of oscilloscope that provide the colour output ..popular makes like agilent ..hp
.etc ..it is used to distinguish between the different frequency bands of oscillation at 2.4ghz or 5ghz

These are the newer ones which are purely digital. You can hook them to a computer using USB and do more analysis of the signal.

As for the colours - I believe there will be a legend for the same.

What could be price of low budget digital oscilloscopes?
Needed for hobby purpose only.

New good ones approx 12k ..u can get at olx or quikr for cheap ..look for the ones with a fixed channel device ..those are more accurate and also the greater the frequency count ..the better it is ...
Regards

And also one more thing go for the pure analog device ...not the digital ones

The digital ones provide more of a filtered output ..whereas the analog ones gives the out as close to the source

Basically, you need to have a good ADC and a high enough sampling rate, else analog is better than digital.

But apart from that, digital is far better than analog anytime.

You can even make your own with some COTS parts. I remember reading up on it in EFY and maybe Hackaday
