Analyzing USB (lemmy.world)

How do people use an oscilloscope to analyze USB packets and such? I saw a video by Ben Eater and the way he did it was by exposing the necessary wires of a USB cable and probing those. Is this standard or are there types out there that have this functionally built-in as some accessory or something?

That sounds like an expensive oscilloscope.

I use an OpenVizsla.

The one Ben Eater was using was a Keysight 200MHz, I think with 2GS/s sampling.
