I am just starting to learn micro controllers and electronics in general. I now find myself in need of a good oscilloscope for a budget of about £200. I believe that I need a minimum bandwidth of around 20 MHz. I have looked at various models, some standalone others USB but I'm not really sure what I should buy.
I would like to monitor the efficiency of my voltage regulators, check serial buses and clock signals etc. Can anybody recommend a model which would suit my requirements and budget?
