Command only Not applicable Not applicable Not applicable
Usage
:TRIGger:LOAD "LogicTrigger", <digInLine>, <digOutLine>, <count>
:TRIGger:LOAD "LogicTrigger", <digInLine>, <digOutLine>, <count>, <clear>
:TRIGger:LOAD "LogicTrigger", <digInLine>, <digOutLine>, <count>, <clear>, <delay>
:TRIGger:LOAD "LogicTrigger", <digInLine>, <digOutLine>, <count>, <clear>, <delay>,
"<bufferName>"
:TRIGger:LOAD "LogicTrigger", <digInLine>, <digOutLine>, <count>, <clear>, <delay>,
"<bufferName>", <readingBlock>
<digInLine>
The digital input line (1 to 6); also the event that the trigger model will wait
on in block 1
<digOutLine>
The digital output line (1 to 6)
<count>
The number of measurements the instrument will make
<clear>
To clear previously detected trigger events when entering the wait block:
ENTer
To immediately act on any previously detected triggers and not clear them
(default): NEVer
<delay>
The delay time before each measurement (167 ns to 10 ks); default is 0 for
no delay
<bufferName>
The name of the reading buffer, which may be a default buffer
(defbuffer1 or defbuffer2) or a user-defined buffer; default is
defbuffer1
<readingBlock>
Define a measure or digitize block for the trigger model; options are:
• ACTive: Add a measure or digitize block to the trigger model based
on the active function; if no option defined, ACTive is used
• MEASure: Adds a measure block to the trigger model
•
DIGitize
: Adds a digitize block to the trigger model
Details
This trigger model waits for a digital input event to occur, makes a measurement, and issues a notify
event. The notify event asserts a digital output line.
After selecting a trigger model template, you can view the trigger model blocks in a graphical format
by pressing the front-panel MENU key and under Trigger, selecting Configure. You can also add or
delete blocks and change trigger model settings from this screen. You can use the
TRIGger:BLOCk:LIST? command to view the trigger model blocks in a list format.
This command replaces the :TRIGger:LOAD:TRIGger:EXTernal command, which is deprecated.
