LogicPort Sample Compression
The LogicPort's real-time hardware sample compression or "transitional sampling" allows it to pack much more data into its sample buffer. Since memory is only written when signals change, the time between signal transitions is essentially "free".  
The trace above shows the LogicPort capturing close to 10 megasamples of data while sampling at 50MHz over a period of nearly 200ms. The trace below shows a very small portion of that same captured data with the time scale reduced (zoomed in) by a factor of 5000.
You won't always capture this much data, but you'll notice that compression tends to work best right when you need it the most. Specifically, it is most effective when you need to capture events separated by significant time intervals while maintaining high resolution.
