- FPGA + FTDI/USB interface provides a very fast configurable data path.
- I understand that external A/D converters MUST be used, and can't be emulated with the FPGA, but even then, that's only like $10/channel at most.
- EZ2SUSB-15: $170, 128 kBps data via USB, external clock but the FPGA is supposed to do up to 200MHz.
- There ARE various FPGA+ADC=oscilloscope projects on the net:
- In addition to being an oscilloscope, the FPGA can be reconfigured to be a semi-logic-analyzer or a signal generator as well.
