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. |
