This isn't a Beagle. When I first read the headline, I was hoping that it would be more than a smart continuity tester.
It seems to be a more comprehensive "Make sure the lines go where they are supposed to" tester. Looks pretty good.
But the devices that test things like transmission speed, are a lot more expensive.
I think that many of the issues that this device tests, can be mitigated by simply buying cables from reputable sources.
Once in the realm of signal integrity, it's true that the price goes straight into lab grade levels.
Even 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.
That's a cheap one. Some of the analyzers can go into 5 figures.
Don't forget the speeds at which modern serial interfaces go. Being able to look at the data, at that speed, requires some serious kit.
