This subsystem programs the CV (constant-voltage mode) function of a single electronic
load.
[SOURce:]VOLTage[:LEVel][:IMMediate], VSET
[SOURce:]VOLTage[:LEVel]:TRIGgered
Channel-Specific Voltage Command/Query. This is an implied keyword that specifies the value of
the programmed voltage level and whether that level is to be applied immediately or on occurrence of
a trigger. If the specified channel is in the CV (Constant-Voltage) Mode, an IMMediate voltage level is
transferred to the input as soon as the command is executed. A TRIGgered level is stored and then
transferred to the electronic load input when a trigger occurs. At that time, the change to the input
level occurs at the slew time presently in effect. Following the trigger event, subsequent triggers will
not affect the input level unless the electronic load has been sent another TRIGgered level command.
If the electronic load is not in the CV (Constant-ower) Mode when an IMMediate or TRIGgered level
command is sent, the programmed levels are saved for the time the electronic load is placed in the
CV mode. Triggered levels are processed by the Voltage Subsystem even when the electronic load is
not in the CV Mode. In this case, the TRIGgered level becomes a stored IMMediate level that takes
effect when the electronic load is again in the CV Mode.
Until they are explicitly programmed, triggered levels will assume their corresponding immediate
levels. For example, if a electronic load is powered up and VOLT is programmed to 10, then
VOLT:TRIG will also be 10 until you program it to another value. Once you program VOLT:TRIG to a
value, it will remain at that regardless of how you subsequently reprogram VOLT. Then, when the
trigger occurs, the VOLT is set to the VOLT:TRIG value.
Note : Setting an IMM voltage level to the same value as the most recent TRIG voltage level will not
deactivate a pending TRIG level. You must use ABORt to deactivate it.
Specify the input voltage level for the VOLTage mode.
Ϯ On
a TRIG[:IMM] command (always)
Ϯ On
receipt of an external trigger signal (if TRIG:SOUR is set to EXTernal)
Ϯ On
receipt of a GPIB
Ϯ On
receipt of an Ethernet trigger signal (if TRIG:SOUR is set to ETHernet)
Ϯ On
receipt of *TRG (unless TRIG:SOUR is set to HOLD)
