Take one oscilloscope probe, and one USB cable. Cut the BNC connector off the oscilloscope probe, and the USB B connector off the USB jack and splice them together.
Mount all the USB <--> analog circuitry inside the scope probe body and/or the USB A connector body. It would essentially compete with all the other USB oscilloscopes out there, but it would be in a single cable design - no extra boxes, etc.
- Is this a product you would like?
- What are your minimum specifications for this type of product?
- What are your ideal specifications for this type of product?
- Would this be any more useful or desirable than the current USB oscilloscopes available?
My biggest concerns are:
- Obtaining the speed necessary to be reasonably useful without requiring a lot of components
- Synchronizing multiple probes into the computer (Getting nS accuracy without wiring the probes together seems problematic...)
- Fitting it all into the form factor and power limitations of a USB port (ideally 100mA unpowered hub ~0.5W)
- Keeping the assembled cost low
I'd appreciate feedback on any or all of the above (what you want vs how to implement it). Ideally it'd be completely open source, but using very tiny surface mount parts it might not be easily assembled by hand.
