USB storage scope interface pcb.
Picture enclosed This is one I designed and built myself. I built two and this is a spare one. It is powered by USB bus. Comes with PC software on a CDROM.
Up to 20KHz sine wave.
The 20KHz is very under optimistic.?? pretty poor performance - you can get that from a decent soundcard and software!
For a maximum input of 20kHz I wouldn't need it......You wont get 1.4 mega samples per second from a sound card.
