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
<CRD> BUS
*RST
Value BUS
Examples TRIG: SOUR BUS TRIGGER: SOURCE BUS
Query Syntax TRIG:SOUR?
Returned Parameters <CRD>
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.
Command Syntax [SOURce]:VOLTage[:LEVel] [:IMMediate][:AMPLitude] <NRf+>
[SOURce]:VOLTage[:lEVel]:TRIGgered[:AMPlitude] <Nrf+>
