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.model.getblocklist() command to view the trigger model blocks in a list format.
Example
-- Set up measure function
smu.measure.func = smu.FUNC_DC_CURRENT
-- Initiate readings
trigger.model.load("LoopUntilEvent", trigger.EVENT_DISPLAY, 50)
Set the instrument to measure current.
Load the LoopUntilEvent trigger model to make measurements until the front panel trigger key is pressed, then
continue to make measurements equal to 50% of the reading buffer size.
