DATS USB Timing Problem?

Simple question: What the heck? I used to be "good with computers," but now I'm not as good as I was. I know that the sample rate for the audio device is correct, and I know that there is some performance/priority tweaking that Windows 10 can do for USB devices, but I don't know where to look.

The screenshot is the result of "Calibrate Test Leads," but I see similar blue fuzz any time I try to do a resistance or impedance measurement. Using the cables provided by Dayton or any other probe leads that I have handy.

I've tried a couple of USB Type-C to Type-B cables, and each of the 4 Type-C ports. This is an all-Type-C machine, and I don't even know where the Dayton USB cable is, but I can look if you really think that's the problem. No devices attached to any other port, running on battery, same result with Windows in Airplane Mode or not.
