Triggering Measurements

Trigger Commands

:TRIGger:IMMediate

The :TRIGger:IMMediate command tells the Test Set to “start a

measurement cycle now.” The type of triggering used depends on the

trigger mode settings. This command is equivalent to a Group Execute

Trigger Command (GET) as defined by IEEE 488.1-1987 or a Trigger

Common Command (*TRG) as defined by IEEE 488.2-1987. The

IMMediate statement is implied and is optional.

Example 5-1 Syntax

:TRIGger:IMMediate

Example 5-2 Example

OUTPUT 714;"TRIG:IMM"

OUTPUT 714;"TRIG"

:ABORt

The :ABORt command tells the Test Set to stop a currently executing

measurement cycle and get ready for a new HP-IB command. If for any

reason a valid measurement cannot be made, this command allows the

control program to terminate the requested measurement and regain

control of the Test Set.

Example 5-3 Syntax

:TRIGger:ABORt

Example 5-4 Example

OUTPUT 714;"TRIG:ABOR"

:MODE

The :MODE command is used to set the Trigger Mode for all active

measurements. The trigger mode is defined by two parameters:

retriggering and settling.

Example 5-5 Retriggering Syntax

:TRIGger:MODE:RETRigger REPetitive

:TRIGger:MODE:RETRigger SINGle

Example 5-6 Retriggering Examples

OUTPUT 714;"TRIG:MODE:RETR REP"

OUTPUT 714;"TRIG:MODE:RETR SING"
