Command Description

SCPI

SYST:LOCAL

is a special purpose

programming command that may be used to
cause source to be set to the local state or to
the remote state. This command has two
noteworthy circumstances under which it may
prove necessary. The first case involves using
RS232 to communicate with the supply, since
the normal GPIB mechanisms for transition
between local and remote and back again do
not exist when using RS232. The other case is
when the REMOTE/LOCAL switch S1-1 is
placed in the ON position—thereby disabling
the GPIB mechanism for transition from remote
to local. The SYST:LOCAL ON command
provides a means for the system computer to
force the source to the local state. Also, the
SYST:LOCAL?

query command is available to

examine the local-remote state of the supply.
And the command SYST:LOCAL OFF may be
used to force supply to the remote state.

N Q

SYST:LOCAL:LOCKOUT

The SYST:LOCAL:LOCKOUT <0|1|OFF|ON>
command provides a means of controlling the
local lockout functionality that is an alternative
to the low level GPIB LLO command.

In contrast, using the GPIB LLO low level
command causes the supply to be placed into
the local lockout state. To place the supply into
the local lockout state, use the
SYST:LOCAL:LOCKOUT

command.

The SYStem:FAULt? query returns 4 numeric values separated by commas. Each value is the
decimal equivalent of the total bit weights for that System Fault Register as described in the
table above.
