Once in the realm of signal integrity, it's true that the price goes straight into lab grade levels.
replyEven in my reputable cables, there are a couple with suspicious continuity issues. I wonder if this could find them.
You could probably build a data transfer tester using an FPGA and some signal processing.
Wasn't aware of this level of testing. $1300 for a Beagle is a big step up.
replyThat's a cheap one. Some of the analyzers can go into 5 figures.
replyDon't forget the speeds at which modern serial interfaces go. Being able to look at the data, at that speed, requires some serious kit.
