EEVblog:
How to find and inspect hidden serial UART terminal ports inside equipment.
Dave finds the uBoot Windows CE UART part in the new Keysight 1000 X-Series oscilloscope and uses the info to find some of the product mode configuration pins. A hardware hack shows that changing product configuration modes in hardware is possible.

vaualbus:
Where we find the photo of the early non production model?

sasquatch:
Is this Keysight trying to do a Rigol? An unauthorised yet acceptable hack?

EEVblog:
I've found the other product set resistors, playing now...  :)
