Default and Reset States
The 34945A allows several types of reset and default actions. Most resets
rely on states stored in non- volatile memory on the remote modules.
Default parameters can be set to ensure the system always returns to a
safe state.
SYSTem:RMODule:RESet
This command is the only command that will reset all remote modules
connected to a slot to the factory defaults. No determination of the
distribution boards present is made. The system is set to the following
