All limit patterns and the pass pattern are sent on digital I/O lines 1 to 4, where 1 is the least
significant bit.
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.
Also see
:TRIGger:BLOCk:LIST? (on page 12-164)
:TRIGger:LOAD "LogicTrigger"
This command loads a predefined trigger model configuration that sets up a digital trigger through the digital I/O.

:TRIGger:LOAD "LogicTrigger", <digInLine>, <digOutLine>, <count>, <clear>, <delay>,
"<bufferName>"
<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
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.
Example
:TRIGger:LOAD "LogicTrigger", 1, 2, 10, ENTer, 0.001, "defbuffer1"
Set up the template to use the digital in line 1 and wait until the wait block is entered to detect the pulse from
digital in line 1 and to trigger measurements.
Pulse digital out line 2 when the measurement is complete.
Make 10 measurements, with a delay of 1 ms before each measurement.
Store the measurements in
defbuffer1
.
