:SYSTem Subsystem
This subsystem collects together the capabilities that are not related to
instrument performance.
:SYSTem:COMMunicate Subtree
The
:SYSTem:COMMunicate
subtree collects together the configuration of the
control/communication interfaces.
The
:SYSTem:COMMunicate:SERial
subtree controls the physical configuration of
the RS-232C port. Any command to change the settings takes effect immediately
upon receipt of the “program message termination.” These settings are stored in
non-volatile memory, and are unaffected by power-on,
*RST
, and
*SAV/*RCL
.
The
:SYSTem:COMMunicate:SERial:TRANsmit
subtree controls parameters
associated with transmission.
The instrument always uses eight data bits, one stop bit, and no parity.
COMMAND
:SYSTem:COMMunicate:GPIB[:SELF]:ADDRess . . . <numeric_value>
Sets the GPIB address that the instrument uses.
REPLY FORMAT
<NR1>
COMMENTS
– The range for
<numeric_value>
is 0 through 30.
– The default setting is address 19.
– This value is unaffected by *RST.
– To change the GPIB address used at power-on, save the instrument settings
using the
*SAV 0
command after changing the GPIB address.
