TRIGger Subsystem
The power supply has a trigger subsystem, so voltage and current values can be
changed when receiving a trigger signal.
Depending on the trigger source selected, this change takes place immediately
(when receiving the trigger signal), or after a time period equal with the delay
you set (a time period from the moment the power supply receives the trigger
signal)
To activate the trigger subsystem you must follow the steps described bellow:
1. Specify the source of the trigger signal. The power supply accepts
a bus trigger or an immediate trigger coming from the remote
interface.
Bus trigger source
*TRG command is considered the trigger signal.
The current and voltage trigger values become the output programmed values
after a time period (from the moment the power supply received the trigger
signal), called trigger delay.
The trigger subsystem must be initiated before sending the trigger signal (for
initiation you mus use the INITIATE command). Otherwise, -211 error is
generated (trigger ignored error).
Immediate trigger source
INITIATE[:IMMEDIATE] command is considered the trigger signal.
The current and voltage trigger values become the output programmed values
immediately after receiving INITIATE command.
In this situation, *TRG command is ignored (the power supply doesn’t do
anything and it doesn’t generate any errors).
After an interface reset or after power on reset, bus trigger source is selected.
2. Program the volt:trig and curr:trig values.
When receiving the trigger signal, the power supply transfers these values to
volt and current programmed values immediatly (if imm trigger source is
selected) or after a period of time equal to the trigger delay programmed value
(if bus trigger source is selected).
