I need to capture high-speed eSPI traffic, what do you recommend?

Question from the Customer:

I’m trying to monitor eSPI traffic at 48 MHz. However, the method I’m currently using degrades the eSPI signals.  To get clean signals, the bus had to be slowed down to 8MHz before it was reliable again. Unfortunately, that does not support the functionalities that I need to verify and support.

In addition, I wa...
