Common IEEE Commands

Trigger

*TRG

This command triggers the instrument. Use the :TRIGger[:SEQuence]:SOURce command to select the trigger source.

The desired measurement has been selected and is waiting. The command causes the system to exit this “waiting” state and go to the “initiated” state. The trigger system is initiated and completes one full trigger cycle. It returns to the “waiting” state on completion of the trigger cycle. See the MEASure subsystem for more information about controlling the measurement process.

The instrument must be in the single measurement mode. If INIT:CONT ON, then the command is ignored. Depending upon the measurement and the number of averages, there may be multiple data acquisitions, with multiple trigger events, for one full trigger cycle.

Remarks:

See also the :INITiate:IMMediate command

Front Panel

Access: Restart

Self Test Query

*TST?

This query performs a full self alignment and returns a number indicating the success of the alignment. A zero is returned if the alignment is successful. Same as CAL[:ALL]? and *CAL?

Front Panel

Access: System, Alignments, Align All Now

Wait-to-Continue

*WAI

This command causes the instrument to wait until all pending commands/processes are completed before executing any additional commands. There is no query form for the command.

The instrument default is to only wait for completion of the internal self-alignment routines. You must set the STATus:OPERation:EVENt resgister if you want to look for the completion of additional processes. See the *OPC? command for more information.

Key Type:

There is no equivalent front panel key.
