I'm wondering if anyone has information about DIY equipment listed in the title. After all, the heart of all those would simply be an ADC?
I'm looking for something that has a bandwidth of atleast 100Mhz that is very simple to do(doesn't have to be fancy). Basically I just need to get the data into the PC... after that its pretty easy to emulate the above.
I figure that one just needs and ADC, a PGA, a probe, and a pic to configure the ADC and PGA. I'm not sure about which interface to use though. I was thinking about USB2.0 or something similar but it would require additional components. (I'm not sure if USB has some type of streaming protocol or not... in any case it probably wouldn't be a good idea unless it is the only device using it). Maybe some type of PCI interface would work?
