:SYSTem:ERRor?   

Syntax   

:SYSTem:ERRor?   

Function    Returns    the    error    number    and    an    error    message    from    the   

error   queue.   See   the   

Error   Queue

   section,   for   a   list   of   error   

numbers   and   their   associated   messages.      

Example   

:SYST:ERR?   

returns:   0,   “No   error”.   

   
:SYSTem:VERSion?   

Syntax   

:SYSTem:VERSion?   

Function    Returns   the   formatted   numeric   value   the   of   the   SCPI   version   

number.   

Example   

:SYST:VERS?   

returns:   1999.0

.

   

   
:SYSTem:COMMunicate:GPIB[:SELF]:ADDRess   

Syntax   

:SYSTem:COMMunicate:GPIB[:SELF]:ADDRess

<space><num

eric_value>   

Function    Sets    the    GPIB    address.    The    factory-­‐set    GPIB    address    is    21.   

When    the    address    is    changed,    the    interface    immediately   
responds   to   the   new   address.   

Example   

:SYST:COMM:GPIB:ADDR   7   

   
:SYSTem:COMMunicate:GPIB[:SELF]:ADDRess?   

Syntax   

:SYSTem:COMMunicate:GPIB[:SELF]:ADDRess

?   

Function    Returns   the   GPIB   address.      

Example   

:SYST:COMM:GPIB:ADDR?

   returns   7.
