Example
trigger.model.load("Empty")
trigger.model.setblock(1, trigger.BLOCK_BUFFER_CLEAR)
trigger.model.setblock(2, trigger.BLOCK_MEASURE)
trigger.model.setblock(3, trigger.BLOCK_BRANCH_COUNTER, 5, 2)
trigger.model.setblock(4, trigger.BLOCK_DELAY_CONSTANT, 1)
trigger.model.setblock(5, trigger.BLOCK_BRANCH_COUNTER, 3, 2)
trigger.model.setblock(6, trigger.BLOCK_RESET_BRANCH_COUNT, 3)
trigger.model.initiate()
waitcomplete()
print(defbuffer1.n)
Reset trigger model settings.
Clear defbuffer1 at the beginning of the trigger model.
Loop and take 5 readings.
Delay a second.
Loop three more times back to block 2.
Reset block 3 to 0.
Start the trigger model and wait for measurements to complete.
Print the number of readings in the buffer.
Output:
15

Turn the source off: smu.OFF
Turn the source on: smu.ON
Details
The source output block determines if the output source is turned on or off when the trigger model
reaches this block.
This block does not determine the settings of the output source (such as the output voltage level and
source delay). The source settings are determined by either the present settings of the instrument or
by a source configuration list.
When you list trigger blocks, this block is listed as SOURCE_OUTPUT.
