NOTE If a Questionable bit is in the proper state, then programming thecorresponding PTR or NTR filter bit to 1 will set the associated EventRegister bit. Standard Commands for Programmable Instruments (SCPI) 101 Command Syntax STATus:QUEStionable:NTRansition STATus:QUEStionable:PTRansition Parameters 0 to 32727 Default Value 0 Examples STAT:QUES:NTR 16 STATUS:QUESTIONABLE:PTR 512 Query Syntax STAT:QUES:NTR? STAT:QUES:PTR? Returned Parameters (Register value) SYST:ERR? 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,N0 ERROR. If more errors are accumulated than the queue can hold, the last error in the queue will be -350,T00 MANY ERRORS. Query Syntax SYSTem:ERRor? Returned Parameters , Examples SYST: ERR? SYSTEM: ERROR? SYST:LANG Switches the interface between its SCPI (TMSL) command language and it compatibility language. Note that the earlier parameter "TMSL" must be used in place of "SCPI". Sending the command causes: . The alternate language to become active and to be stored in nonvolatile memory. . The power supply to reset and clear the storage and error registers. NOTE After sending the SYST:LANG command, do not send another command or turn the supply off for at least five seconds. If the power supply is shut off, it will resume operation in the last-selected language when power is restored. Command Syntax SYSTem:LANGuage {TMSL|COMPatibility} Syntax is the same, regardless of the present language Parameters TMSL or COMPatibility Default Value TMSL or last selected language Examples SYST:LANG TMSL SYSTEM:LANGUAGE COMPATIBILITY Query Syntax SYSTem:LANGuage? Returned Paramters TMSL or COMP 102 Standard Commands for Programmable Instruments (SCPI) Trigger Subsystem This subsystem controls remote triggering of the power supply. TRIG[:IMM] When the trigger subsystem is armed, TRIG generates a trigger signal. The trigger will then: 1. Initiate the output change from the pending level to the immediate level (see CURR[:LEV]:TRIG and VOLT[:LEV]:TRIG). 2. Clear the WTG bit in the Status Operation Condition register. 3. If INIT:CONT has been sent, the trigger subsystem is immediately rearmed for subsequent triggers. This means that as soon as it is cleared, the WTG bit is again set to 1. Command Syntax TRIGer[:IMMediate] Examples TRIG TRIGGER:IMMEDIATE TRIG:SOUR Sets the trigger source to bus commands. Since the power supply has no other trigger source than the GP-IB bus, this command need not be used. It is included in the command set to provide programming compatibility with other instruments (such as the Agilent Electronic Load family) that may have more than one trigger source. Command Syntax TRIGer:SOURce BUS Parameters BUS *RST Value BUS Examples TRIG: SOUR BUS TRIGGER: SOURCE BUS Query Syntax TRIG:SOUR? Returned Parameters BUS Voltage Subsystem This subsystem programs the output voltage of the power supply. VOLT[:LEV] Sets the immediate voltage level or the pending triggered voltage level of the power supply. The immediate level is the voltage programmed for the output terminals. The pending triggered voltage level is a stored value that will be transferred to the output when a trigger occurs. If no pending triggered level has been programmed, then the immediate command programs both levels to the same value. Once a triggered level has been programmed, it is unaffected by subsequent changes to the immediate level.

[SOURce]:VOLTage[LEVel]:TRIGger [:AMPLitude]? MAX [SOURce]:VOLTage[:LEVel]:TRIGger [:AMPLitude]? MIN Returned Parameters VOLT? and VOLT:TRIG? return presently programmed voltage levels. If the TRIG level is not programmed, both returned values are the same. VOLT MAX? and VOLT MIN? return the maximum and minimum programmable immediate voltage levels. VOLT:TRIG? MAX and VOLT:TRIG? MIN return the maximum and minimum programmable triggered voltage levels. VOLT:PROT[:AMPL]? Queries the overvoltage protection level of the power supply. The overvoltage protection level can only be set from the front panel OVP potentiometer. Query Syntax [SOURce]:VOLTage:PROTection [:A...
