I need a build or buy a system that can record digital transmissions on a 4-bit proprietary bus. The bus transmissions occur roughly every
300us, and the transmissions are short 10MHz bursts. Through whatever means necessary, I need to store a minute's worth of this data to a file that I can access from a PC. Of course, this would require lower data storage volume if the device is able to sense transitions on the bus, instead of just storing regular, time-sampled data.I've considered buying National Instruments' High Speed Digital I/O boards, but -- I figured I should ask around to see if there are better, more turn-key solutions available. Maybe something like a specialized logic analyzer?
Any help will be greatly appreciated. -Zach
