Manual triggering example
The following code pauses a script and prompts the operator to press the TRIG key when they are
ready to continue. If the TRIG key is not pressed, the test will continue after waiting 10 minutes
(600 seconds).
display.clear()
display.trigger.clear()
display.setcursor(1, 1, 0)
display.settext(“Take a Break”)
display.setcursor(2, 1, 0)
display.settext(“Press TRIG to continue”)
display.trigger.wait(600)
display.clear()
Digital I/O triggering interactive example
The following example configures digital I/O line 2 as an input trigger and digital I/O line 14 as an
output trigger. It commands the Series 2600A to wait for an external input trigger on digital I/O line
2. If a trigger event occurs, the Series 2600A outputs an external trigger on digital I/O line 14. If no
trigger event is received on digital I/O line 2, the test is aborted.
-- Configure digital I/O lines 2 and 14 for input trigger detection and
-- output trigger generation, respectively.
digio.trigger[2].mode = digio.TRIG_RISINGA
digio.trigger[2].clear()
digio.trigger[14].mode = digio.TRIG_FALLING
digio.trigger[14].pulsewidth = 0.0001
--Wait 15 seconds for a trigger event to occur on digital I/O line 2
trigInput = digio.trigger[2].wait(15)
-- If a trigger event occurs on digital I/O line 2, assert an output
-- trigger on digital I/O line 14. If a trigger event does not occur,
-- then turn off the output of smua and issue a message on the front
-- panel display.
if trigInput == true then
digio.trigger[14].assert()
else
smua.source.output = smua.OUTPUT_OFF
display.screen = display.USER
display.clear()
display.setcursor(1, 1)
display.settext("No trigger received. Test aborted.")
exit()
end
