Best oscilloscope choice?

[Paul-R]

The teacher might take an interest and turn it into a school project. (You could mention the Bedini SG saga).

Also, sometimes they can have scopes which are VERY good. If there are several, you could get a very useful idea of what you need and what you want.

Thanks for your advise TinselKoala. If i don't find a better choice I'll go for the Hankel. I think i have to confirm if the manuals are with it befoer i buy as well as checking the minumun pc specs required. (and of course, probes too). An good old model sounds like a good option, but I don't know anything about  them so if I find something that seems like a good choice I'll ask you guys before.

One last thing. Can you explain that thing about the two channels? Why do I need tow of them? (as i just said i dont know so much about it)

Thanks!!

PAul R. Your idea sounds good. That could be a whole experiment project for students. I'll think about it.

Thanks!

I think TK will suggest that you are likely to be wanting to compare two different points in your circuit at exactly the same time.

If you have a slow running project, like a pulsed motor, there is a software scope called Winscope where the probe plugs into your sound card. It is free.

What I want to do is to built a Hartley oscillator circuit, and I want to check if the real frecuecy of this circuit matches with the thorical one already calculated. It something very simple compare with most of the things I can find in forums abut electronics. So Will I need to channels for that anyway? I guested he meant to compare the signal of my circuit with a given "control" signal. Am I wrong?
