Digital I/O triggering interactive example
The programming example below illustrates how to configure digital I/O line 2 as an input trigger and
digital I/O line 14 as an output trigger. The 2606B to wait for an external input trigger on digital I/O line
2. If a trigger event occurs, the 2606B 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, turn off the output of smua and issue a message
-- on the virtual 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

Hardware trigger modes

You can use different hardware trigger modes for digital I/O and TSP-Link
hardware triggers to integrate Keithley instruments and non-Keithley instruments in a test system.
The 2606B supports 14 digital I/O lines and three TSP-Link synchronization lines that can be used for
input or output triggering. For additional information about the hardware trigger modes, see
command reference
For direct control of the line state, use the bypass trigger mode.
