Programming Commands and Examples ESG Family Signal Generators

:TRIGger Subsystem

The trigger subsystem is used to set the controls and the parameters associated with

triggering a sweep in the signal generator.

Abort

:ABORt

There is no query for this command.

This command causes the sweep in progress to abort and reset, causes the bit error rate

(BER) measurement in progress to abort and set the BER measurement state to Off. If

INIT:CONT is ON, then the sweep will immediately reinitiate. The pending operation flag

(affecting *OPC, *WAI, and *OPC?) will undergo a transition once the sweep has been

reset.

Continuous Sweep

:INITiate:CONTinuous[:ALL] ON|OFF|1|0

:INITiate:CONTinuous[:ALL]?

This command activates the continuous sweep mode. The choices are On (1) or Off (0).

Modifying this value does not affect the sweep in progress. Executing this command with

ON causes the sweep to be automatically restarted at the end of the previous sweep.

Executing this command with OFF causes the sweep to wait until an

:INITiate[:IMMediate] command is sent to reinitiate the sweep.

*RST Value: Off

External Trigger On Slope

:TRIGger[:SEQuence]:SLOPe POSitive|NEGative

:TRIGger[:SEQuence]:SLOPe?

This command sets the polarity of the slope present at the TRIGGER IN connector that

will trigger a sweep in the signal generator. The choices are Positive edge and Negative

edge.

*RST Value: Positive

Immediate Trigger

:TRIGger[:SEQuence][:IMMediate]

There is no query for this command.

This command has no effect unless sweep is waiting for a trigger. If sweep is waiting for a

trigger (sweep or point-to-point) then this command triggers the sweep, regardless of other

settings in the :SWEep subsystem.
