Hey i was wondering if anyone here had one? I am thinking about buying it but Im just afraid that it might fry the usb port . http://www.parallax.com/detail.asp?product_id=28119 i was looking at this one but the sampling rate isn't that high =/. So its either pay 160 for all that or pay 3x amount for a better oscilloscope . I plan to be doing logic circuits and radio circuits so i am afraid that the sampling rate wouldn't suffice. So yeah any ideas? Thanks a bunch =).
