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"
or
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"
