Select the Transient Trigger Source
NOTE
An immediate trigger command either from the front panel or over the bus will
generate an immediate trigger regardless of the trigger source.
Unless you are using the front panel menu or a TRIG:TRAN command
to trigger the output, select a trigger source from the following:
Bus
Selects GPIB device trigger, *TRG, or <GET> (Group Execute Trigger).
Pin<n>
Selects a pin on the external port connector as the trigger source.
<n> specifies the pin number. The selected pin must be configured as a
Trigger Input in order to be used as a trigger source (see Appendix B).
Transient
<n> Selects the output channel’s transient system as the trigger source.
<n> specifies the channel. When you select a channel, you must also set up
that channel’s transient system to generate a trigger out signal. Refer to
“Generate Trigger Out Signals”.
Use the following commands to select a trigger source:
Front Panel: SCPI Command:
To select Bus triggers, select
Transient\TrigSource. Select Bus
.
To select Digital pin triggers, select
Transient\TrigSource. Then select
one of the digital port pins.
To select Transient output triggers,
select Transient\TrigSource. Then
select one of the output channels.
To select Bus triggers for output 1:
TRIG:TRAN:SOUR BUS,(@1)
To select Digital pin triggers:
TRIG:TRAN:SOUR PIN<n>,(@1)
where n is the pin number.
To select Transient output triggers:
TRIG:TRAN:SOUR TRAN<n>,(@1)
where n is the output channel that
will generate the trigger signal.
Initiate the Transient Trigger System
Next, you must initiate or enable the transient trigger system.
When the power system is turned on, the trigger system is in the idle
state. In this state, the trigger system is disabled, ignoring all triggers.
Initiating the trigger system moves it from the idle state to the
initiated state, which enables the power system to receive triggers. To
initiate the trigger system, use:
Front Panel: SCPI Command:
Select the Transient\Control.
Scroll to Initiate and press Select.
To initiate the output trigger system
for all four outputs:
INIT:TRAN (@1:4)
After a trigger is received and the action completes, the trigger
system returns to the idle state. Thus, it will be necessary to enable
the system each time a triggered action is desired.
