Trigger the Output

The trigger system is waiting for a trigger signal in the initiated state. You can immediately trigger the output as follows:

Front Panel:

SCPI Command:

Select Transient\Control.

To generate an immediate trigger on

Select Trigger to generate an

channel 1:

immediate trigger signal regardless

TRIG:TRAN (@1)

of the trigger source setting.

Alternatively, if the trigger source is

 

BUS, you can also program a *TRG or

 

an IEEE-488 <get> command

When a trigger is received, the triggered functions are set to their programmed trigger levels. When the triggered actions are completed, the trigger system returns to the idle state.

As previously discussed, a trigger can also be generated by another output channel or by a trigger signal applied to an input pin on the digital port connector. If any of these systems are configured as the trigger source, the instrument will wait indefinitely for the trigger signal. If the trigger does not occur, you must manually return the trigger system to the idle state.

The following commands return the trigger system to the idle state:

Front Panel:

SCPI Command:

Select Transient\Control.

ABOR:TRAN (@1)

Scroll to and select Abort.

 

Generate Trigger Out Signals

Each output channel can generate trigger signals that can be used by other output channels, or routed to a pin on the digital port that has been configured as a trigger output (TOUT). Use the following commands to program transient trigger signals that are generated when an output Step occurs:

Front Panel:

SCPI Command:

Use the Channel key to select the

channel that is the trigger source.

to generate a trigger signal, use

Select Transient\Step.

STEP:TOUT ON,(@3)

Check Enable Trigger Output. Then

 

press Select.
