4.5.18 SYSTem Subsystem
The SYSTem group of commands is used to control system-level functions not directly related to instrument measure-
ment performance. SYSTem commands are used to return error codes or messages from the power meter error queue,
control hardware features (backlight and keybeep), set the command language, and configure communication param-
eters for the GPIB and serial interfaces.
SYSTem:VERSion
Description:
Return the SCPI version compliance claimed.
Syntax:
SYSTem:VERSion?
Returns:
Version Code as <year.version> YYYY.V (will return 1990.0)
Valid Modes:
Any
SYSTem:ERRor
Description:
Returns the next queued error code number followed by a quoted ASCII text string describ-
ing the error. Note that errors are stored in a “first-in-first-out” queue, so if more than one
error have occurred, repeating this command will report the errors in the sequence they
happened. The action of reading the error will clear that error, so once the most recent error
has been read, any more queries will report a code of zero, and “No Error”. See section 4.9
for a more detailed description of the error codes that may be returned.
Syntax:
SYSTem:ERRor[:NEXT]?
Returns:
<numeric error code>, “QUOTED ERROR DESCRIPTION”
Valid Modes:
Any
SYSTem:LANGuage
Description:
Set or return the remote interface “language”, SCPI (SCPI compliant), or BOON (native
mode). The instrument always powers up in the SCPI state. Activating the BOON language
extension will enable the 4530 Native Mode commands (see paragraph 4.5.5), while still
supporting all SCPI commands. Native mode is useful for reporting high-speed measure-
ments over the remote interface with a minimum overhead.
Syntax:
SYSTem:LANGuage <asc>
Argument:
<asc> = SCPI, BOON
Valid Modes:
Any
SYSTem:BEEP
Description:
Set or return the on/off state of the key beep: ON = audible, OFF = silent.
Syntax:
SYSTem:BEEP <asc>
Argument:
<asc> = ON, OFF
Valid Modes:
Any
