> Decent quality cable testers can be had for like $20,000.

See the discusison linked to.

Trust me, my interest was piqued by that thread and I went down the rabbit warren with Mr Google and spent far too much time on the subject. I looked at the various manufacturers and the setups required.

TL;DR: To start with, you need fancy harness assemblies. Then you need to plug those harnesses into very, very expensive equipment.

You're not going to find anything for $20k. High-throughput USB-cable testing simply can't be done the same way copper CAT6 certification can with a 20k Fluke.

For those who want to play with Mr Google, some manufacturers from my notes: Wilder Technologies, Allion, Keysight, Tektronix, Teledyne LeCroy

Here's one blog post I uncovered during my researches: https://www.keysight.com/blogs/en/tech/bench/2023/02/17/powe...
