Simple, and doesn't require anything real-time. It just requires a
data-acquisition board that has a timer and a FIFO, which most modern
boards do. I routinely acquire with a 2 us sampling interval, on a
486/33, with a NI AT-MIO-16E-2. (It can't, however, keep up with
waveform generation at the same time.)
