Wouldn’t it be nice to have an oscilloscope, spectrum analyser and function generator in one instrument without doing enormous damage to your wallet? And in addition, this instrument will not take up space on your crowded desk or workbench and does not require a separate power supply? This sounds too good to be true! But it is possible, provided you already own a Windows-PC with a sound card. Granted, the frequency range is limited to the audio range and the accuracy depends on your sound card, but for 18 pounds or so this is certainly a very handy and desirable measuring instrument.
