Triggering Commands
The power supply’s triggering system allows a change in
voltage and current when receiving a trigger, to select a
trigger source, and to insert a trigger. Triggering the power
supply is a multi- step process.
• First, you must specify the source from which the power
supply will accept the trigger. The power supply will
accept a bus (software) trigger or an immediate trigger
from the remote interface.
• Then, you can set the time delay between the detection of
the trigger on the specified trigger source and the start of
any corresponding output change. Notice that the time
delay is valid for only the bus trigger source.
• Finally, you must provide an INITiate command. If the
IMMediate source is selected, the selected output is set
to the triggered level immediately. But if the trigger
source is the bus, the power supply is set to the triggered
level after receiving the Group Execute Trigger (GET) or
*TRG command.
Trigger source choices
You must specify the source from which the power supply
will accept a trigger. The trigger is stored in volatile
memory; the source is set to bus when the power supply has
been turned off or after a remote interface reset.
Bus (software) triggering
• To select the bus trigger source, send the following
command.
