SYSTem Subsystem
System commands control system functions that are not directly related to output control,
measurement, or status functions. Note that IEEE-488 Common commands also control system
functions such as self-test, saving and recalling states, and others.
SYSTem:COMMunicate:LAN:CONTrol?
SYSTem:COMMunicate:TCPip:CONTrol?
Returns the initial socket control connection port number. This connection is used to send and receive
commands and queries. Unlike the data socket, which uses a fixed port number, the control socket
port number varies and must be obtained using these queries.
Parameter
(none)
Query the Control connection port number:
SYST:COMM:LAN:CONT? or SYST:COMM:TCP:CONT?
SYSTem:COMMunicate:RLSTate LOCal|REMote|RWLock
SYSTem:COMMunicate:RLSTate?
Configures the remote/local state of the instrument. Remote and local do the same thing and are
included for compatibility with other products. LOCal sets instrument to front panel control. REMote
sets the instrument to front panel control. RWLock disables the front panel keys. The instrument can
only be controlled via the remote interface. This programmable setting is completely independent from
the front panel lock/unlock function.
Parameter
LOCal|REMote|RWLock , *RST LOCal
Sets the remote/local state to remote: SYST:COMM:RLST REM
The remote/local state is unaffected by *RST or any SCPI commands other than SYSTem:COMMu-
l
nicate:RLState.
The remote/local instrument state can also be set by other interface commands over the GPIB and
l
some other I/O interface.
When multiple remote programming interfaces are active, the interface with the most recently
l
changed remote/local state determines the instrument's remote/local state.
