I think you are onto something but `syst:prot:sscr ON` returns "Character data not allowed"


1 or 0, returns "Numeric data not allowed"

There is a system flag SEALED_STATE_KEY that stores the "sealed" state of the scope. When the scope is in the "sealed" state, some of the interesting SYSTem SCPI commands are discarded.

To check if a scope is (un)sealed, one can use:

SYSTem:PRODuction:SEAL?

If it returns 1 (ON), means it is "SEALED"    :(

Not optimal, but I wonder if there is a console port on the pcb? If,so I wonder if it has a shell, and what user it has

That's a good idea, but I don't think I have ever opened something up to try to hack it and didn't end up destroying it.. :(

Wonder if someone has a guide or video if there are any traps to taking it apart.
