Memory - protection
These commands enable you to either write protect a block of stores (or a single store) to prevent
accidental overwriting or to unprotect it. For a single store set both start and stop numbers the
same. Note that any protection applied to RAM will be lost once the instrument has been switched
off.
MPROT [not used alone]
:START Set the start of the memory block which is to be protected/unprotected
:STOP Set the end of the memory block which is to be protected/unprotected
Data type : Decimal Numeric Program Data
Allowed suffices : None
Default suffix : None
:ON Set memory protection ON for the selected memory block
:OFF Set memory protection OFF (i.e. unprotected) for the selected memory
block
Data type : None
Allowed suffices : None
Default suffix : None
Examples: MPROT:START 100;STOP 150
