From what I recall, you can get the measurements while it’s stuck in the loop trying to boot.

I performed the Center Frequency Test (2.1.2) - it was pretty close, but made a minor tweak. Same for the 2us Single-Shot Test (2.1.3) - it was off by a little bit so I made an adjustment. I tested this during a boot attempt.
However, for the 1us Single-Shot Test (2.1.4), I am not seeing any activity on the scope for A14, pin 3. What do you think might cause that?
Tried writing another disk for the heck of it, same result.
