The following figure shows the trigger setup for this example.
Figure 67: Single pulse triggering
Single pulse example code
-- Generate a single 500 us, 5 V pulse.
-- Configure a single-point voltage list sweep.
smua.trigger.source.listv({5})
smua.trigger.source.action = smua.ENABLE
smua.trigger.measure.action = smua.DISABLE
-- Configure other source parameters for best timing possible.
smua.trigger.source.limiti = 0.1
smua.source.rangev = 5
-- Configure timer parameters to output a single 500 us pulse.
trigger.timer[1].delay = 0.0005
trigger.timer[1].count = 1
trigger.timer[1].passthrough = false
-- Trigger timer when the SMU passes through the ARM layer.
trigger.timer[1].stimulus = smua.trigger.ARMED_EVENT_ID
-- Configure source action to start immediately.
smua.trigger.source.stimulus = 0
-- Configure endpulse action to achieve a pulse.
smua.trigger.endpulse.action = smua.SOURCE_IDLE
smua.trigger.endpulse.stimulus = trigger.timer[1].EVENT_ID
-- Set appropriate counts of trigger model.
smua.trigger.count = 1
smua.trigger.arm.count = 1
-- Turn on output and trigger SMU to output a single pulse.
smua.source.output = smua.OUTPUT_ON
smua.trigger.initiate()
-- Wait for the sweep to complete.
