I didn't even know such things exist. When I wanted to know the delays of 7400-series logic gates, I built a logic analyzer using Arduino and stroboscopic effects which provided resolution on order of 1 ns. But with CCD it seems that it could be done much easier, and allowed to measure exact voltage and not just logic levels.
