Language Dictionary 45

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 B. 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 oper ation 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)

Trigger Subsystem

This subsystem controls remote triggering of the power supply.

TRIG

When the trigger subsystem is enabled, TRIG generates a trigger signal. The trigger will then:

1. Initiate a pending level change as specified by CURR[:LEV]:TRIG or VOLT[:LEV]:TRIG.

2. Clear the WTG bit in the Status Operation Condition register.

3. If INIT:CONT has been given, the trigger subsystem is immediately re-enable d for subsequent triggers. As soon as it

is cleared, the WTG bit is again set to 1.

Command Syntax TRIGger[:IMMediate]

Parameters (None)

Examples TRIG TRIGGER:IMMEDIATE

Query Syntax (None)

Related Commands ABOR CURR:TRIG INIT *TRG VOLT:TRIG
