Usage
trigger.model.setblock(blockNumber, trigger.BLOCK_DELAY_DYNAMIC, userDelay)
blockNumber
The sequence of the block in the trigger model
userDelay
The number of the user delay to recall:
• trigger.USER_DELAY_Sn, where n is the number of the user
delay (1 to 5) set by smu.measure.userdelay[N]
• trigger.USER_DELAY_Sn, where n is the number of the user
delay (1 to 5) set by smu.source.userdelay[
N
]
Details
When the trigger model reaches a delay building block, it stops the trigger model for the amount of time set by
the delay.
The delay time is set by the user delay command.
Example
smu.source.userdelay[1] = 5
trigger.model.setblock(1, trigger.BLOCK_SOURCE_OUTPUT, smu.ON)
trigger.model.setblock(2, trigger.BLOCK_DELAY_DYNAMIC, trigger.USER_DELAY_S1)
trigger.model.setblock(3, trigger.BLOCK_MEASURE)
trigger.model.setblock(4, trigger.BLOCK_SOURCE_OUTPUT, smu.OFF)
trigger.model.setblock(5, trigger.BLOCK_BRANCH_COUNTER, 10, 1)
trigger.model.initiate()
Set user delay for source 1 to 5 seconds.
Set trigger block 1 to turn the source output on.
Set trigger block 2 to a dynamic delay that calls source user delay 1.
Set trigger block 3 to make a measurement.
Set trigger block 4 to turn the source output off.
Set trigger block 5 to branch to block 1 ten times.
