Trigger model operation
Once the instrument is taken out of idle, operation proceeds through the trigger model down to the
device action.
Control Source — As shown in Figure 3, a control source is used to hold up operation until the
programmed event occurs. The control source options are explained as follows:
•
HOLD — Only the TRIG:IMM command will generate a trigger in HOLD mode. All other trigger
commands are ignored.
•
MANual — Event detection is satisfied by pressing the TRIG key.
•
TIMer — This generates triggers that are in synchronization with the electronic load's internal
oscillator as the trigger source. The internal oscillator begins running as soon as this command
is executed. Use TRIG:TIM to program the oscillator period.
•
EXTernal — Event detection is satisfied when an input trigger via the TRIGGER LINK connector is
received by the electronic load.
•
BUS — Event detection is satisfied when a bus trigger (GET or *TRG) is received by the
electronic load.
Delay — A programmable delay is available after the event detection. The delay can be manually set
from 0 to 999999.999 seconds.
