Designing a professional digital oscilloscope is a pretty complex task wich makes them also pretty expensive. Therefore I concluded it’s nothing more than a daydream to design one of those.
It’s far more realistic to limit the design of this instrument to something a bit more realistic. If you connect something like the JYE Tech Oscilloscopeto the network then you still have a pretty usefull instrument.It’s basic specifications are:
- Single channel.
- External trig available.
- Max sample rate 5Ms/s.
- Analog bandwidth 1MHz.
- Vertical sensitivity 100mV/Div – 5V/Div.
- Input impedance 1MOhm.
- Max input voltage 50Vpp.
It’s also an affordable product. A kit can be bought for EUR30 to EUR35. For example at: Watterott in Germany. On the website of JYE Tech you can find a worldwide distributor list of this simple but useful instrument.
