System Commands

System commands query error messages and software versions, and program system language functions.

SYST:ERR?

This query returns the next error number followed by its corresponding error message string from the remote programming error queue. The queue is a FIFO (first-in, first-out) buffer that stores errors as they occur. As it is read, each error is removed from the queue. When all errors have been read, the query returns 0,NO ERROR. If more errors are accumulated than the queue can hold, the last error in the queue will be -350,TOO MANY ERRORS (see Appendix D for other error codes).

You can use the power supply front panel key to read errors from the queue. Errors generated at the front panel are not put into the queue but appear immediately on the display.

Query Syntax	SYSTem:ERRor?
Parameters	(None)
Returned Parameters	<NRI>,<SRD>
Examples	SYST:ERR? SYSTEM:ERROR?
Related Commands	(None)

SYST:LANG

This command switches the interface between its SCPI (TMSL) command language and its compatibility language. The compatability language is provided for emulation of older power supply systems and is described in Appendix G. Sending the command causes:

∙The alternate language to become active and to be stored in nonvolatile memory.

∙The power supply to reset to the state stored in Location 0.

If the power supply is shut off, it will resume operation in the last-selected language when power is restored.

Command Syntax	SYSTem:LANGuage <string>
	Syntax is the same, regardless of the present language.
Parameters	TMSL COMPatibility
	Note:	Parameter TMSL must be used in place of SCPI.
Default Value	TMSL or last selected language.
Examples	SYST:LANG TMSL SYSTEM:LANGUAGE COMPATIBILITY
Query Syntax	SYSTem:LANGuage?
Returned Parameters	<CRD>	TMSL COMP
Related Commands	(None)

SYST:VERS?

This query returns the SCPI version number to which the power supply complies. The returned value is of the form YYYY.V, where YYYY represents the year and V is the revision number for that year.

Query Syntax	SYSTem:VERSion?
Parameters	(none)
Returned Parameters	<NR2>
Examples	SYST:VERS? SYSTEM:VERSION?
Related Commands	(None)
