Why on earth is so much more expensive than an arbitrary pair of devices that could max out a cable?

Think about it.

You need to generate a precise, calibrated, 40GHz signal, transmit it, then precisely measure the returned signal for phase, amplitude, and waveform integrity -at that speed.

Oscilloscopes and logic analyzers that run at that speed, are damn expensive.
