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-enabled 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

TRIG:SOUR

This command selects the trigger source. Since the power supply has no other trigger source than the GPIB 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 <CRD>
Parameters	BUS
*RST Value	BUS
Examples	TRIG:SOUR BUS TRIGGER:SOURCE BUS
Query Syntax	TRIGger:SOURce?
Returned Parameters	BUS
Related Commands	RST TRG TRIG[:IMM]

Voltage Subsystem

This subsystem programs the output voltage of the power supply.

VOLT

VOLT:TRIG

These commands set 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 level is a stored voltage value that is transferred to the output terminals when a trigger occurs. A pending triggered level is unaffected by subsequent VOLT commands and remains in effect until the trigger subsystem receives a trigger or an ABORt command is given. If there is no pending VOLT:TRIG level, then the query form returns the VOLT level. In order for VOLT:TRIG to be executed, the trigger subsystem must be initiated (see INITiate).
