Summary of Oscilloscope using AVR microcontroller
The article discusses the challenges of designing a professional digital oscilloscope due to complexity and cost. Instead, it suggests using an affordable and practical alternative: the JYE Tech Oscilloscope. This single-channel device offers features like external trigger, 5Ms/s max sample rate, 1MHz bandwidth, and 1MOhm input impedance. It is budget-friendly, available as a kit for around EUR30-35, with distributors worldwide, making it a realistic tool for basic oscilloscope needs.
Parts used in the JYE Tech Oscilloscope Project:
- AVR microcontroller
- Oscilloscope kit components (specific parts vary per kit)
- Input circuit for voltage measurement
- External trigger input circuitry
- Display unit (likely LCD or similar)
- Power supply components
- Sampling and analog bandwidth circuitry
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.
