Yes, I mean sampling. I want to see the eye-diagrams preferably, using a DIY device. It should be possible, perhaps using delay-lines (as now on the HN frontpage).
Also, if a device like this exists, then maybe someone can write an open-source tool to compute the bit-error-rate from digital inputs. Or write some Wireshark extension to do decoding of raw signals.
This Keysight company makes nice tools but they are out of reach of hobbyists and small companies, and cheaper tools should be possible since we're all having USB3 devices in our computers already (digital ones, ok).
