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 Typical Return
(0 if sockets not supported)
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. This programmable setting is completely independent
from the front panel lock/unlock function.
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.
Parameter Typical Return
LOCal|REMote|RWLock , *RST LOCal LOC, REM, or RWL
Sets the remote/local state to remote: SYST:COMM:RLST REM
l The remote/local state is unaffected by *RST or any SCPI commands other than SYSTem:COMMu-
nicate:RLState.
l The remote/local instrument state can also be set by other interface commands over the GPIB
and some other I/O interface.
l When multiple remote programming interfaces are active, the interface with the most recently
changed remote/local state determines the instrument’s remote/local state.
SYSTem:DATE <yyyy>,<mm>,<dd>
SYSTem:DATE?
Sets the date of the system clock. Specify the year, month, and day. Setting the date causes the
optional BBR logging function to stop and then start using the new date.
Parameter Typical Return
<yyyy,<mm>,<dd> <date>
Sets the date (January 31, 2012): SYST:DATE 2012,01,31
