This is a very simple design of digital oscilloscope. The original project comes from EP 8/2004. The only difference I’ve made was adding RS232 to USB converter to use it with my laptop. Schematic can by found here: analogue and digital.

There can be seen analogue input section with OPA2350 amplifiers and relays as voltage dividers. ADC is fast television IC, TDA8703. Digital data goes through DS89C420, via USB to PC application showing results.

It is harder and harder to find RS232 connector in modern computers. That’s why I decided to make this converter. I doubt there is at least one computer without USB.
