hello,
i bought one of these recently,
http://www.ebay.co.uk/itm/PC-USB-2C...731978?hash=item1a014951ca:g:nWgAAOSwYGFUs8Eh
i set the dds to 20Mhz on sine wave and tried to measure it on the oscilloscope and the oscilloscope couldnt measure it, it showed 20Hz instead. i dont know if this is how it would show it.
is there some way to test the accuracy of this device. i dont have any other test equipment and i am new to testing things.
any advice on this would be helpful. i cant afford much so getting an expensive £100 or more for an oscilloscope alone, not including dds and other stuff that comes with this.
thanks
simon
