USB Oscilloscope

Which are they?

I have a PicoScope and it is very good for the money IMO, but I also had a ocilloscope multi-meter type thing that could connect to the PC to chart the data and it wasn't that accurate.
 
It looks rather useless since it's upper range is only 3KHz. You wouldn't be able to see switch mode PSU noise for example.
 
Keep your eye on ebay,a few people i know have picked up old,but fully working dual beam scopes for around the £50 mark.
 
You can use a sound card to do some scope work, but again it only goes up to 20KHz, or if you have a 96KHz or 192KHz card a bit higher. Even a 192KHz card doesn't really go high enough for proper usage though.

I guess the basis is an ADC, but what software do you use. Is there some Free software?

I like the idea of an old "proper " scope, but it might be difficult to carry to Cyprus - unless I can find one in a junk shop here!
